2001-2005 Honda Civic 1.7L L4 MT Cold Air Intake Kit
A manual-transmission 2001-2005 Honda Civic 1.7L responds well to better airflow, and this Flashark cold air intake kit delivers it with black powder-coated aluminum piping and a reusable red cone filter. Swapping out the factory airbox and intake tube lets the 1.7L D17 four-cylinder pull in more cool air, which sharpens throttle response and gives the car a deeper, more aggressive induction note under acceleration.
Typical intake-only gains for this application are approximately 5-10 hp and 6-8% torque, and the biggest day-to-day change usually comes from the sharper throttle and the sound rather than peak power. The kit installs with common hand tools in under 60 minutes, and fuel economy may improve slightly under steady driving.

- Under 60-minute install: Bolts on with common hand tools, so the swap can be finished in under an hour.
- Washable, reusable filter: Micro cotton gauze media rinses clean with water or mild soap and can be reused instead of replaced.
- Expected output range: Approximately 5-10 hp and 6-8% torque, with a deeper, more aggressive intake sound under acceleration.

Who This Kit Is For
This Flashark cold air intake replaces the factory airbox and intake tube on 2001-2005 Honda Civic 1.7L four-cylinder models with a manual transmission. It suits owners who want sharper throttle response, a deeper intake tone under acceleration, and a washable filter they clean instead of replace.
For you if:
- You drive a 2001-2005 Civic with the 1.7L engine and a manual transmission.
- You want a first bolt-on upgrade that runs on hand tools and finishes in under an hour.
- You prefer a reusable washable filter over disposable paper elements.
- You want a more aggressive induction sound without changing the exhaust.
Not for you if:
- Your Civic is an automatic — this kit is built for manual-transmission cars only.
- You drive a 2002-2005 Civic Si, which uses a 2.0L K-series engine and needs its own intake.
- You need a factory-style replacement filter or hose instead of a performance intake.
- You plan deep-water crossings without relocating the filter higher.
- You expect a large peak-power jump from an intake on a naturally aspirated 1.7L.

Check Before Ordering
- Vehicle and transmission: This kit fits 2001-2005 Honda Civic 1.7L L4 models with a manual transmission. Automatic Civics use different intake routing, brackets, hoses, and clearance, so they are not covered. If your car is not covered, message us before ordering, or browse the rest of our Honda cold air intake kits.
- Intake type: This is a Cold Air Intake kit that replaces the factory airbox and the intake tube ahead of the throttle body. The factory intake manifold stays bolted to the engine. If you are weighing an open short-ram setup against a cold air setup, our short ram vs cold air intake Civic comparison covers the real differences in heat soak and power.
- Filter and maintenance: The kit uses a red micro cotton gauze cone filter that can be washed with water or mild soap and reused. Rinse it when dirt builds up between the pleats, let it dry completely, and reinstall it before driving.
- Sensors and connections: The kit is designed so the factory intake-air sensor and breather hoses reconnect at their original locations. Confirm every clamp is tight and every vacuum or breather line is connected before start-up.
- Emissions: This kit carries no CARB Executive Order number, so it is not street-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.
- Install space and water: Install takes common hand tools and under 60 minutes, and access through the bumper or inner-fender area may be needed depending on the final filter position. The filter sits low enough that deep water crossings can draw water into the engine, so avoid deep puddles and flooded roads unless you relocate the filter higher.
What's in the Box

Product FAQ
A1: 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. If you live in a CARB state, look for a kit that carries a valid EO number. Outside those states, check your local emissions and inspection requirements before installing. A2: It fits 2001, 2002, 2003, 2004, and 2005 Honda Civic models with the 1.7L four-cylinder engine and a manual transmission. Seventh-generation Civics use several D17-series variants depending on trim and market, so compare your factory intake tube, throttle-body connection, breather ports, and sensor layout with the product photos before ordering. A3: No. This kit is built for 2001-2005 Honda Civic 1.7L manual-transmission cars only, where MT means manual transmission. Automatic Civics use different intake routing, brackets, hoses, and available clearance, so the kit will not line up correctly. A4: No. The 2002-2005 Civic Si runs a 2.0L K-series engine rather than the 1.7L engine used in most other seventh-generation Civics. Its throttle body, intake routing, engine-bay layout, and mounting points are different, so it needs an intake designed specifically for the Si. Browse our Civic Si kits if that is your car. A5: No. This is a cold air intake kit, not an intake manifold. It replaces the factory airbox and the intake tubing ahead of the throttle body. The original intake manifold bolted to the cylinder head stays on the engine. A6: Typical intake-only gains for this application are approximately 5-10 hp and 6-8% torque. Actual results depend on engine condition, intake-air temperature, exhaust modifications, ECU calibration, fuel quality, and testing method. On a mostly stock 1.7L Civic, the sharper throttle and induction sound are usually more noticeable than the peak horsepower increase, so treat it as a supporting bolt-on rather than a major power modification. A7: 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 bolt-on replacement that keeps the factory sensors and connections in their original locations. A8: No tune is required when the kit is installed by itself on a compatible, otherwise stock Civic. The factory ECU can make limited fuel adjustments during normal operation. Tuning becomes more useful once the engine also has a header, full exhaust, camshaft, larger throttle body, forced induction, or other substantial airflow changes. A9: A correctly installed intake should not automatically cause a check engine light. Common causes after installation include an intake leak, a loose clamp, a disconnected breather or vacuum hose, damaged sensor wiring, or an incorrectly seated intake-air sensor. Read the diagnostic code and inspect every hose and connection before replacing parts — our guide to rough idle after a cold air intake install walks through the usual fixes. A10: Yes. The aluminum intake pipe and open cone filter generally produce a deeper, more noticeable induction sound during acceleration. The engine may stay relatively quiet at light throttle, but the intake tone grows more aggressive as engine speed and throttle opening increase. A11: The kit includes a performance cold air intake system with black powder-coated aluminum piping and a red washable cone filter. Before removing the factory airbox, compare all couplers, clamps, hoses, brackets, and hardware against the product images, and keep the original parts until installation is complete. A12: Flashark states the kit can be installed with common tools in under 60 minutes. Installation generally involves removing the factory airbox and resonator, routing the new intake pipe, connecting the breather hoses, and securing the filter and clamps. Access through the bumper or inner-fender area may be required depending on the final filter position. A13: Normal rain is not a problem when the filter is securely mounted and the factory splash shields and inner-fender liners stay in place. Avoid deep puddles, flooded roads, missing splash protection, and direct pressure-washing around the filter. A low-mounted filter that becomes submerged can draw water into the engine and cause hydrolock. A14: It may improve gas mileage slightly, but an MPG gain is not guaranteed. Fuel economy depends more on driving style, traffic, tire pressure, engine maintenance, vehicle load, and throttle use. Drivers who accelerate harder to hear the intake may see little or no fuel-economy change. A15: Inspect the red micro cotton gauze filter regularly and clean it once dirt starts building up between the pleats. It can be washed with water or mild soap and reused. Let the filter dry completely before reinstalling it, and never run the engine without the filter securely attached.2001-2005 Honda Civic 1.7L Cold Air Intake FAQs
