Want your 2012-2015 Honda Civic to breathe as it should? This Flashark Cold Air Intake Kit replaces the factory's restrictive airbox with a smooth-flowing aluminum intake system and a high-flow red dry filter — giving you sharper throttle response, better mid-range torque, and that crisp induction sound the stock setup completely muffles. All with a true bolt-on install that takes about an hour with basic hand tools.
Your 1.8L SOHC engine was choking on warm, stagnant air from the factory airbox. This kit routes cooler, denser air directly into your throttle body using a Φ76mm (3") large-bore main pipe paired with a Φ70mm secondary pipe and a straight-through red cone filter. The result: your Civic pulls harder from 3,000 RPM and sounds alive every time you floor it.

Q: Will this fit my 2013 Honda Civic EX Coupe with the 1.8L?
A: Yes — this is a direct bolt-on for all 2012-2015 Civic DX, EX, LX, SE, and Touring models with the 1.8L SOHC engine, including both sedan and coupe.
Q: Does it fit the 2012-2015 Civic Si?
A: No. The Civic Si uses a 2.4L K24Z7 engine with a completely different intake configuration. This kit is only for the 1.8L SOHC.
Q: How much horsepower will I actually gain?
A: Expect 5-10 wheel horsepower on a stock 1.8L. The biggest difference you'll feel is throttle response and mid-range pull between 3,000-5,500 RPM.
Q: Do I need a tune or programmer?
A: No tune required. The factory ECU adapts automatically to the increased airflow. Install it, clear your ECU if needed (disconnect battery for 5 minutes), and drive.
Q: Will it throw a check engine light?
A: Not if installed correctly. Make sure the breather hose (D24-d16×230mm) is connected to your factory PCV port and all clamps are tight. A vacuum leak is the #1 cause of CEL after intake installs.
Q: Is the filter dry or oiled?
A: Dry filter — no oil required. Tap out loose debris, spray with filter cleaner, rinse gently with low-pressure water from the inside out, air dry completely, reinstall. Do every 10,000-15,000 miles.
Q: Is it safe in rain?
A: Normal rain driving is fine. Avoid deep standing water — if the filter ingests water, it can hydrolock your engine.

Frequently Asked Questions About the 2012–2015 Honda Civic 1.8L Cold Air Intake Kit (DX / EX / LX / SE / Touring)
Q1: What vehicles does this 2012–2015 Honda Civic cold air intake kit fit?
A1: This cold air intake kit is designed for 2012, 2013, 2014, and 2015 Honda Civic models including DX, LX, EX, SE, and Touring trims equipped with the 1.8L R18 engine. Always confirm your engine (R18Z1 or equivalent) before purchasing.
Q2: Will this intake fit a 2012 Honda Civic LX or EX?
A2: Yes. It fits both 2012 Civic LX and EX models with the 1.8L engine. These trims share the same intake layout, making installation straightforward with factory mounting points.
Q3: Does this cold air intake fit a 2013–2015 Honda Civic 1.8L?
A3: Yes. The kit is compatible with 2013, 2014, and 2015 Honda Civic 1.8L models including DX, LX, EX, SE, and Touring trims as long as the engine is the 1.8L R18 series.
Q4: Will this intake increase horsepower on a Honda Civic 1.8L?
A4: Yes, but gains are modest. Most users see around 5–10 horsepower improvement depending on conditions and supporting modifications such as exhaust or throttle body upgrades. The most noticeable change is improved throttle response and engine sound.
Q5: Does this Civic cold air intake require a tune?
A5: No tune is required. The 9th generation Civic uses a MAP (Manifold Absolute Pressure) sensor system, which automatically adapts to airflow changes without recalibration for basic bolt-on intakes.
Q6: Will this intake cause a check engine light (CEL)?
A6: A properly installed intake will not normally trigger a CEL. Issues usually come from loose clamps, vacuum leaks, or incorrect sensor connection rather than the intake itself.
Q7: Is this intake compatible with automatic and manual transmissions?
A7: Yes. Transmission type does not affect intake compatibility. As long as the vehicle has the 1.8L engine, the kit will fit both automatic and manual Civic models.
Q8: Will this cold air intake improve fuel economy?
A8: Fuel economy improvements are possible but not guaranteed. Under steady driving conditions, slight MPG gains may occur, but aggressive driving or frequent acceleration can offset any efficiency benefits.
Q9: Will this intake make my Honda Civic louder?
A9: Yes. You will hear a more aggressive intake sound during acceleration, especially at higher RPM. It enhances engine tone without changing exhaust sound.
Q10: Is this intake safe for daily driving?
A10: Yes, it is designed for daily use. When installed correctly, it maintains safe air-fuel operation and does not negatively affect drivability.
Q11: What is the difference between cold air intake and short ram intake for Civic?
A11: A cold air intake draws cooler air from outside the engine bay for denser airflow, while a short ram intake sits closer to the engine and may pull warmer air but is easier to install. Cold air setups generally offer better performance potential.
Q12: Can this intake get water damage or hydrolock risk?
A12: Like any exposed filter system, driving through deep water can increase the risk of water ingestion. Normal rain and street driving are safe, but avoid submerging the filter.
Q13: Is installation difficult for beginners?
A13: No. Installation is straightforward and usually takes 30–60 minutes with basic hand tools. No cutting or permanent modification is required.
Q14: Does the Honda Civic 1.8L use a MAF sensor?
A14: No. The 2012–2015 Civic 1.8L uses a MAP sensor system, not a MAF sensor. This makes it less sensitive to airflow changes from intake upgrades.
Q15: Is this intake worth it for a stock Honda Civic?
A15: Yes for drivers who want better throttle response, improved engine sound, and a sportier feel. However, it should be seen as a supporting modification rather than a major horsepower upgrade on a stock engine.
