2012-2015 Honda Civic 1.8L SOHC Cold Air Intake Kit
Built for 2012, 2013, 2014, and 2015 Honda Civic sedans and coupes powered by the 1.8L SOHC R-series engine, this Flashark cold air intake kit replaces the factory airbox and the factory intake tube to route cooler, denser air into the throttle body. The included heat shield and powder-coated aluminum piping are sized specifically for the 9th-generation Civic engine bay, so the kit bolts to factory mounting points without cutting or fabricating — most installs finish in about 60 minutes with a basic socket set.
If you drive a DX, EX, LX, Touring, or SE trim with the 1.8L engine and want a more audible intake tone plus the option to service a reusable dry filter instead of replacing paper elements every service interval, this kit is engineered for that exact configuration. The MAF sensor and intake air temperature sensor are retained at their original locations and bores, so the factory calibration envelope is not modified by the install.

Key Features
- True Cold Air Design with Dual-Diameter Aluminum Piping: Routes cooler, denser air through a Φ76 mm (3 in) main pipe paired with a Φ70 mm secondary pipe, both powder-coated matte black, replacing the factory airbox and intake tube without cutting or fabrication.
- Washable Dry Cone Air Filter: 120 mm top / 155 mm base / 130 mm height with a Φ76 mm inlet; red dry cotton gauze that requires no oil — clean with soap and water and reuse rather than replacing paper elements every service interval.
- Precision Silicone Couplers: Includes one Φ70 → Φ76 reducer coupler and one Φ76 straight coupler for sealed joints at the throttle body and the filter neck.
- Complete Hardware Kit: Two air filter clamps, three narrow band clamps, one mini clamp, four M6 bolts, four washers, and two M6 anti-vibration rubber mounts are included — no extra parts run to the hardware store.
- Vehicle-Specific Aluminum Mounting Brackets: Two aluminum brackets (76 × 18 × 1.5 mm and 165 × 18 × 1.5 mm) bolt to factory mounting points so the install stays bolt-on with no fabrication.
- Factory PCV Routing with Breather Hose: The included D24-d16 × 230 mm breather hose connects to the factory PCV system to preserve stock crankcase ventilation. The MAF and intake air temperature sensors are retained at their original locations and bores.
Who This Kit Is For
This Flashark Cold Air Intake Kit is designed for the 2012, 2013, 2014, and 2015 Honda Civic sedan and coupe with the 1.8L SOHC R-series engine, including DX, LX, EX, EX-L, SE, and Touring trims.
✓ For you if… you want a more audible intake tone under acceleration · you prefer a washable dry filter you can clean and reuse instead of disposable paper elements · you want a bolt-on install you can finish in your driveway in about an hour with a socket set · you have confirmed your state and county emissions rules below.
✗ Not for you if… you drive a 2012–2015 Honda Civic Si (the 2.4L K24Z7 engine is a different configuration — see the Si-specific kit) · you drive a Civic Hybrid, CNG, or natural-gas trim (different intake geometry) · you need an OEM-replacement airbox or intake hose (this is a complete kit replacement) · you live in California or a CARB-adopting state and require an EO-numbered kit (see Compliance Notice below).

2012-2015 Honda Civic 1.8L Cold Air Intake Kit FAQs
Q1: Is this cold air intake legal in my state?
A1: This kit does not carry a CARB Executive Order (EO) number, so it is not legal for sale or use in California or any other state that adopts California emissions standards (CARB-adopting states). It is intended for off-road, competition, or use in states that follow federal EPA emissions rules. Always confirm your state and county emissions rules before installing this kit on a street-driven vehicle.
Q2: Will this fit my 2012–2015 Honda Civic?
A2: This kit is designed for 2012, 2013, 2014, and 2015 Honda Civic sedans and coupes equipped with the 1.8L SOHC R-series engine (including R18Z1) in DX, LX, EX, EX-L, SE, and Touring trims. Civic Si (2.4L K24Z7), Civic Hybrid, CNG, and 2016+ models are not covered by this SKU. If your Civic is not in the fitment table above, message us with your year, trim, and engine code before ordering.
Q3: Will this fit a Honda Civic Si?
A3: No. The 2012–2015 Civic Si uses the 2.4L K24Z7 engine with a different intake geometry, throttle body, and mounting layout. This kit is engineered for the 1.8L SOHC R-series engine only. Browse the Si-specific kit in the Honda Civic Cold Air Intake Kits collection.
Q4: Will this fit a Honda Civic Hybrid?
A4: No. The Civic Hybrid uses a different intake manifold and airbox geometry than the standard 1.8L gasoline Civic. This kit does not cover Hybrid, CNG, or natural-gas trims.
Q5: How much horsepower will this add?
A5: Expected output range is approximately +3 to +10 hp and +3 to +10 lb-ft of torque for naturally aspirated 1.8L engines. Actual results vary with the vehicle's condition, ECU calibration, supporting hardware, and installation quality. The factory MAF sensor and intake air temperature sensor are retained at their original locations, so the engine management system operates within its stock calibration envelope.
Q6: Will a cold air intake improve my MPG?
A6: Fuel economy is dominated by driving habits. An intake alone cannot guarantee a measurable MPG gain. The main benefits of this kit are sharper throttle response and a more audible intake tone under acceleration.
Q7: Will this void my factory warranty?
A7: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless the manufacturer proves the part caused the failure. This kit is designed as a direct bolt-on replacement that retains the factory MAF sensor, IAT sensor, breather routing, and throttle body connection, so the engine management system operates within the OEM design envelope.
Q8: Will this throw a check engine light (CEL)?
A8: The kit retains the factory MAF sensor and intake air temperature sensor at their original locations and bores, which keeps the MAF calibration within the OEM design envelope. A CEL is most often the result of an intake leak at a coupler joint, a sensor that has been disturbed, or an over-oiled filter — none of which apply when this dry filter kit is installed correctly.
Q9: Do I need a tune after installing?
A9: No tune is required for this bolt-on install. The kit retains the factory MAF sensor, IAT sensor, and throttle body connection, so the engine operates within its stock calibration envelope.
Q10: Is this kit safe in rain or off-road conditions?
A10: Normal rain driving is fine. The filter sits low in the engine bay, so avoid deep water crossings. Water ingestion can cause hydrolock and severe engine damage. If you regularly drive through standing water, consider a high-mounted or relocation filter setup.
Q11: How do I clean the dry filter?
A11: The included filter is a dry synthetic element that requires no oil. To clean, remove the filter, tap out debris, then wash gently with mild soap and water. Allow it to air dry completely before reinstalling. Do not use oil on this filter.
Q12: What does the intake sound like?
A12: You will hear a deeper intake tone under acceleration; at cruise, it quiets down. Sound is subjective, so the cleanest way to compare this open-element cold air intake against a short ram or a sealed airbox is to read our Honda Civic Cold Air Intake vs Short Ram Intake guide before ordering.
Q13: How long does installation take?
A13: Most installs finish in about 60 minutes with a basic socket set, screwdrivers, and pliers. The kit bolts to factory mounting points and includes all required couplers, clamps, and hardware. No drilling or fabrication is required.
