Cold Air Intake Kit for 2012-2015 Honda Civic DX/EX/LX/Touring/SE Sedan & Coupe 1.8L SOHC Naturally Aspirated

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.

Key Features

True Cold Air Design — the intake pipe routes to a cooler zone away from the exhaust manifold, pulling denser air for better combustion and measurable power gains

High-Flow Red Cone Air Filter — 120mm top / 155mm base / 130mm height, Φ76mm inlet, red dry cotton gauze (no oil required); washes clean with soap and water and lasts the life of your car

Dual-Diameter Aluminum Pipes — Φ76mm main intake pipe plus Φ70mm secondary pipe, both powder-coated in matte black; engineered for smooth airflow transition without turbulence

Precision Silicone Couplers — includes 1× Φ70→Φ76 reducer coupler and 1× Φ76 straight coupler for leak-free connections at every joint

Full Hardware Kit in the Box — 2× air filter clamps, 3× narrow band clamps, 1× mini clamp, 4× M6 bolts, 4× washers, 2× anti-vibration rubber mounts with M6 threads

2× Aluminum Mounting Brackets — vehicle-specific bracket geometry (76×18×1.5mm and 165×18×1.5mm) bolts to factory mounting points; no drilling, no fabrication

Breather Hose Included — D24-d16×230mm breather tube connects to your factory PCV system; no check engine light, no codes

Direct Bolt-On Fit — everything lines up with factory holes. About 60 minutes in your driveway with a socket set.

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.
