Key Features
- Two-piece aluminum tubing: Mandrel-bent 6061 aluminum sections with a corrosion-resistant black powder-coated finish replace the factory airbox and intake tract. The smooth tube path is intended to reduce intake restriction; results depend on the vehicle and installation.
- Reusable dry cone filter: Red cotton-gauze media can be washed and reused without filter oil, avoiding the over-oiling risk of an oiled filter. It is intended to capture approximately 95% or more airborne particles under appropriate test conditions; actual filtration depends on particle size and maintenance.
- Direct-fit mounting layout: The kit uses factory mounting points and includes connection hardware, with no cutting or drilling expected on the specified factory-style configuration. Installation time is typically about 45 minutes within the broader 30–60 minute range.
- Factory sensor connections: The kit is intended for the Civic's original MAP-based fuel-control layout and existing sensor connections. Check every hose and electrical connection after installation; a check-engine light can have several causes.
- More audible induction: Expect a deeper intake tone under acceleration than the factory resonator setup. D16Y8-equipped applications may make the VTEC transition more noticeable; sound varies by vehicle and driving conditions.
- Responsive driving feel: The less restrictive intake path is intended to improve throttle response through low and mid rpm, including the roughly 3,000–6,000 rpm range, and can make acceleration feel more immediate. Expected output is approximately 5–10 hp on a near-stock D-series application, with results affected by engine condition, calibration, installation, and supporting parts.
Who This Kit Is For
This kit is for 1996–1998 Honda Civic EX, HX, Si, and EX-R owners with the matching 1.6L SOHC engine and factory-style intake layout who want a washable filter, more audible induction, and a bolt-on intake change. It can suit a daily driver or a broader bolt-on build that also includes exhaust or suspension work. If your vehicle has a different engine, a nonstandard throttle-body connection, or an altered intake route, contact Flashark before ordering.

Check Before Ordering
- Vehicle: Match the year, trim, engine code, and factory-style intake layout to the Fitment table. Regional Si and EX-R configurations may differ; confirm the engine and routing on your car.
- Intake configuration: This kit uses an open cone filter and two tube sections. It does not include a heat shield. Confirm available space around the filter and moving or hot components.
- Connections: Compare the factory hose, vacuum, sensor, and throttle-body connections with the kit before installation. The 3.0-inch product-page size does not identify a specific connection bore.
- Filter care: Wash and fully dry the reusable dry filter as its care instructions direct; do not apply filter oil. Inspect it more often in dusty conditions.
- Installation and water: Basic hand tools are expected. Secure all clamps, couplers, hoses, and mounts; check for leaks and clearance. Avoid deep water crossings because water ingestion can cause hydrolock and severe engine damage.
- Emissions: See the Compliance Notice below before ordering or using this kit on public roads.

Product FAQ
A1: Not legal for sale or use in California (and other CARB-adopting states). FLIS25011 has no CARB Executive Order. Check your local emissions rules before ordering. A2: The Fitment table covers 1996–1998 Civic EX, HX, Si, and EX-R with the specified 1.6L SOHC engine codes. Check the engine code and factory-style intake layout on your car. Contact us to verify your year, model, and engine before ordering if any detail differs. A3: The 1998 EX and HX are included with their respective engine codes in the Fitment table. Confirm the original intake and throttle-body layout remains in place. Contact us if the engine or intake has been changed. A4: The Fitment table includes 1996–1998 Si and EX-R configurations with the D16Y8 engine. Regional versions may differ in routing or equipment. Check your vehicle's engine code and intake layout before ordering. A5: Typical intake-only gains for this application are approximately 5–10 hp. Actual results depend on vehicle condition, ECU calibration, installation, and supporting hardware. Throttle feel and sound may be more noticeable than peak output. A6: MPG is dominated by driving habits; an intake alone can't guarantee a measurable gain. Expect the main benefit as throttle response and intake tone rather than fuel economy. A7: A bolt-on installation that keeps the factory sensor and vacuum connections typically does not require a tune. Check those connections and the engine's operation after installation. Other modifications or a changed intake configuration may call for different calibration. A8: A check-engine light can have several causes after intake work, including a loose clamp, vacuum leak, or disconnected sensor. Recheck every connection and read any stored diagnostic code. Correct installation reduces avoidable leaks but does not rule out a warning light. A9: This product is sold as a cold air intake kit and uses a two-piece tube with an open cone filter. It does not include a heat shield. Check the filter's installed location on your vehicle when comparing intake layouts. A10: Both manual and automatic transmissions are supported. The year, trim, engine code, and factory-style intake layout still need to match. Contact us if the vehicle has a different regional configuration. A11: Expect a deeper intake tone under acceleration than the factory intake. The D16Y8 VTEC transition may sound more pronounced in matching applications. Sound varies with the car, exhaust, and driving conditions. A12: A typical installation takes approximately 30–60 minutes with basic hand tools, with about 45 minutes as a common estimate. Remove the factory airbox and intake tract, mount the new sections, and check every clamp, hose, and sensor connection. Vehicle condition and experience affect the time needed. A13: Normal rain calls for the same care you would use with any exposed intake filter. Avoid deep water crossings; water ingestion can cause hydrolock and severe engine damage. Inspect the filter location and intake connections after wet driving. A14: Yes. The included dry cotton-gauze cone filter is washable and reusable. Follow its cleaning instructions, let it dry fully, and do not apply filter oil. A15: Check clamps, couplers, vacuum lines, sensor connections, mounting points, and clearance from heat or moving parts. Make sure the tubing is secure and there are no intake leaks. Recheck the installation if the engine runs abnormally or shows a warning light.1996–1998 Honda Civic 1.6L SOHC Cold Air Intake FAQs
