2016–2021 Honda Civic 1.5L Turbo Cold Air Intake Kit (Open & Enclosed)
If you drive a 2016–2021 Honda Civic with the 1.5L turbocharged four-cylinder, this cold air intake kit lets you pick the character you want from the intake instead of settling for one design. The Open Intake (No Airbox) runs an exposed cone filter and is designed for a more noticeable turbo spool, induction, and bypass-valve sound. The Enclosed Intake (With Airbox) surrounds the filter with an airbox that helps isolate it from radiant engine-bay heat and gives the install a more factory-style appearance. Both versions replace the factory intake with a mandrel-bent aluminum tube and an oversized washable cone filter, so you clean and reuse the filter instead of replacing it.
Fitment follows the version you choose: the Open Intake is covered for 2016–2021 Honda Civic 1.5L Turbo models, while the Enclosed Intake is covered for 2016–2019 and is not intended for the Civic Si. Both kits are built around your factory MAF sensor, and the intake tube is mandrel-bent so the internal airflow path stays smooth instead of restrictive.

Key Features
- Two intake designs in one listing: the Open Intake (No Airbox) runs an exposed cone filter for a more noticeable turbo spool, induction, and bypass-valve sound, while the Enclosed Intake (With Airbox) surrounds the filter with an airbox that helps isolate it from radiant engine-bay heat and gives the install a more factory-style appearance.
- Replaces the factory intake with a mandrel-bent aluminum tube: the kit swaps the factory intake assembly for precision-formed aluminum tubing and an oversized cone filter, maintaining smooth airflow and reducing turbulence on the way to the 1.5L turbocharged engine.
- Oversized washable and reusable oiled cone filter: the filter traps contaminants while letting the engine breathe, and it is cleaned and re-oiled rather than replaced at every service.
- Long filter service interval: under normal driving conditions the filter is designed for approximately 100,000 miles of service — inspect it regularly, clean it more often in dusty environments, and let it dry fully before reinstalling.
- Built around your factory MAF sensor: the kit is designed to keep the factory MAF sensor in the intake instead of adding a new sensor or separate adapter hardware, which keeps the factory connection intact.
Who This Kit Is For
This Flashark cold air intake replaces the factory intake on 2016–2021 Honda Civic models with the 1.5L turbocharged four-cylinder — the Enclosed Intake option is covered through the 2019 model year. It is for owners who want a more audible turbo and induction soundtrack, a washable filter they maintain themselves, and an intake swap that keeps the factory MAF sensor in place.
✓ For you if… you drive a 2016–2021 Civic 1.5L Turbo and want more turbo spool and bypass-valve sound · you would rather clean and reuse a cone filter than keep replacing elements · you want a real choice between an exposed filter and an enclosed airbox · you are building out the 1.5T and want airflow handled first.
✗ Not for you if… your Civic runs the 2.0L naturally aspirated engine, which this kit is not built for · you drive a Civic Si and want the enclosed-airbox version, which does not fit the Si · you expect a guaranteed MPG gain · you regularly ford deep standing water without relocating the filter (see the hydrolock note below).

Check Before Ordering
① Vehicle: exact fit for 2016–2021 Honda Civic models with the 1.5L turbocharged four-cylinder on the Open Intake, and 2016–2019 on the Enclosed Intake. The 2.0L naturally aspirated Civic is not compatible, and the Enclosed Intake does not fit the Civic Si — Si owners should confirm the Open Intake with our team before ordering. If your Civic is not covered above, browse the Honda cold air intake range or message us with your VIN.
② Intake version: the Open Intake (No Airbox) leaves the cone filter exposed for the most noticeable sound and the simplest layout. The Enclosed Intake (With Airbox) adds an airbox around the filter to help separate it from radiant engine-bay heat and to keep the engine bay looking closer to factory. Pick the version that matches your model year and your sound-versus-heat priority before adding to cart.
③ Filter care: the included cone filter is oiled and reusable. Inspect it at each oil change, clean it once dirt starts building up, let it dry completely, and re-oil it lightly — over-oiling can coat the MAF sensor.
④ Sensors and supporting mods: the kit is built around your factory MAF sensor, so the sensor transfers into the intake rather than being replaced. Check every clamp and coupler for a proper seal before you start the engine. If you are pushing the 1.5T further, an oil catch can for the 2016–2021 Honda Civic 1.5T is a common companion to intake and boost upgrades.
⑤ Compliance: this kit does not carry a CARB Executive Order number, so it is not legal for sale or use in California and other CARB-adopting states. Check your state and local rules before ordering — see the Compliance Notice below.
⑥ Water and environment: a low-mounted filter can take in water if the intake becomes submerged. Avoid deep standing water and flooded roads — water ingestion can cause hydrolock and severe engine damage. Keep the factory splash shields and underbody panels in place, and inspect the filter after unusually heavy water exposure.

2016–2021 Honda Civic 1.5L Turbo Cold Air Intake FAQs
Q1: Is this cold air intake legal in my state?
A1: Not legal for sale or use in California (and other CARB-adopting states). This kit does not carry a CARB Executive Order number, so it cannot be installed on a vehicle registered for street or highway use in California or the other states that have adopted CARB emissions requirements. Confirm your state and local rules before ordering.
Q2: Which Honda Civic models does each version fit?
A2: The Open Intake (No Airbox) is designed for 2016–2021 Honda Civic models equipped with the 1.5L turbocharged inline-four. The Enclosed Intake (With Airbox) is designed for 2016–2019 Honda Civic 1.5L Turbo models and does not fit the Civic Si. Neither version is intended for the 2.0L naturally aspirated Civic. Verify your model year, engine, and selected version before ordering.
Q3: What is the difference between the open intake and the enclosed intake?
A3: The open intake runs an exposed performance filter and is designed to produce a more noticeable turbo spool, induction, and bypass-valve sound. The enclosed version surrounds the filter with an airbox that helps isolate it from radiant engine-bay heat and gives the installation a more factory-style appearance, for a more controlled balance between sound and heat isolation. The two versions also have different fitment ranges, so choose according to your Civic's year and trim. If you are weighing an open short-ram layout against a boxed cold-air design more broadly, our Short Ram vs Cold Air Intake for Civic comparison covers the power, heat-soak, and sound trade-offs between the two.
Q4: Does this cold air intake fit a 2016 Honda Civic 1.5 Turbo?
A4: Yes. Compatible 2016 Honda Civic models with the 1.5L turbocharged engine are covered by both the open-intake and enclosed-airbox options. It is not intended for a naturally aspirated 2.0L Civic, because the intake routing, sensor layout, and pipe dimensions are different.
Q5: Does this intake fit a 2017 Honda Civic 1.5L Turbo?
A5: Yes. A compatible 2017 Honda Civic with the 1.5L turbo engine is covered by both intake styles. Confirm that the vehicle has the turbocharged 1.5L engine rather than the naturally aspirated 2.0L engine before purchasing.
Q6: Will this cold air intake fit a 2020 or 2021 Honda Civic?
A6: The Open Intake (No Airbox) covers 2020 and 2021 Honda Civic 1.5L Turbo models. The Enclosed Intake (With Airbox) is covered only through the 2019 model year, so it should not be ordered for a 2020 or 2021 Civic unless updated compatibility is confirmed with our team.
Q7: Does this cold air intake fit the 2017–2020 Honda Civic Si?
A7: The Enclosed Intake (With Airbox) specifically does not fit the Civic Si. Because intake routing and calibration requirements can vary between the standard 1.5T Civic and the Si, Si owners should confirm compatibility for the Open Intake (No Airbox) with our team before ordering rather than assuming both versions fit.
Q8: Will this intake fit a Honda Civic with the 2.0L non-turbo engine?
A8: No. This intake is designed for the 1.5L turbocharged Civic engine and is not intended for 2.0L naturally aspirated models. A 2.0L Civic uses different intake plumbing, mounting points, and airflow requirements, so it needs an intake engineered for that engine — browse Honda Civic cold air intake kits for the engine-specific options.
Q9: Does a 2016–2021 Civic 1.5T cold air intake require a tune?
A9: A tune may not be required when the intake uses the correct sensor housing dimensions and is installed properly, but the 1.5T Civic can be sensitive to changes in MAF airflow. After installation, monitor idle quality, fuel trims, drivability, and warning lights. A professional tune may be beneficial when the intake is combined with a downpipe, intercooler, higher boost, or other performance modifications.
Q10: Will installing the intake cause a check engine light?
A10: A correctly installed intake should not automatically trigger a check engine light, but warning lights can appear if the MAF sensor is installed backward, a connector is loose, a coupler leaks, a hose is disconnected, or the sensor housing changes airflow readings beyond the ECU's normal correction range. If a light appears, read the diagnostic code and inspect the installation before continuing to drive aggressively. Our rough idle after cold air intake installation guide walks through the usual causes in order.
Q11: How much horsepower can a cold air intake add to a Civic 1.5 Turbo?
A11: Typical intake-only gains for this application are approximately +5 to +15 hp and +5 to +15 lb-ft. Actual results depend on vehicle condition, ambient temperature, ECU calibration, fuel quality, installation, and supporting hardware. On an otherwise stock Civic, the most noticeable changes are often sharper throttle response, stronger induction sound, and less restrictive airflow rather than a large peak horsepower increase. A tuned vehicle may make better use of the additional airflow.
Q12: Is an open intake or an enclosed intake better for a daily-driven Civic?
A12: The better choice depends on your priorities. An open intake suits drivers who want stronger turbo and induction sound, easier filter access, and a more visible engine-bay upgrade. An enclosed intake is often preferable for daily driving in hot conditions, because the airbox provides additional heat separation and helps shield the filter from radiant underhood heat. Any exposed filter can absorb more engine-bay heat while the car is idling or moving slowly, and that temperature increase usually falls once the vehicle is moving and fresh airflow reaches the intake. An upgraded intercooler has a more direct effect on charge-air temperature after the turbo. Fitment still has to be checked, because the enclosed version does not cover every year or the Civic Si.
Q13: Can rain or water damage the engine with this intake installed?
A13: Normal rain should not cause a problem when the intake, splash shields, and underbody panels are correctly installed. However, avoid deep standing water and flooded roads, because a low-mounted filter can ingest water if it becomes submerged. Water ingestion can cause hydrolock and severe engine damage, so inspect the filter after unusually heavy water exposure.
Q14: Is the included air filter washable and reusable?
A14: Yes. The kit includes an oversized washable and reusable oiled filter. Under normal driving conditions the filter is designed for extended service, but it should still be inspected regularly. Clean it more often in dusty environments, allow it to dry completely, and apply only the correct amount of filter oil before reinstalling it.
Q15: Will this intake void my factory warranty?
A15: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless it is proven to have caused the failure. This kit is designed as a direct replacement for the factory intake that keeps the factory sensors and connections.
