Cold Air Intake Kit for 1994-2001 Acura Integra GS RS LS

Fitment

In North America, the Integra was sold only as an Acura. The Japanese-market Honda Integra (DA/DC2/DC4 chassis codes sold in JDM) is a different vehicle and is not covered by this kit. The Integra GS-R (B18C1 VTEC) and Integra Type R (B18C5 VTEC) use different intake-manifold geometry and hose routing and are not listed for this SKU; choose an intake specifically designed for those trims.

1994-2001 Acura Integra LS Cold Air Intake FAQs

Q1: Is this cold air intake legal in my state?

A1: This kit does not carry a CARB Executive Order, so it is not legal for sale or use on public roads in California or other CARB-adopting states. In non-CARB states, install and use rules vary by county and local emissions program; confirm your local rules before installing on a street-driven vehicle.

Q2: Will this fit my Acura Integra?

A2: Exact fit for 1994-2001 Acura Integra LS, GS, and RS with the 1.8L B18B1 non-VTEC engine. The GS-R (B18C1 VTEC) and Type R (B18C5 VTEC) are not listed because they use a different intake-manifold geometry and hose routing. The North American Integra was sold only as an Acura; the Japanese-market Honda Integra (DA/DC/DC2 chassis codes) is a different vehicle and is not covered by this kit. If the engine or chassis has been swapped, message us on the contact page before ordering.

Q3: How much horsepower will this cold air intake add?

A3: Estimated output range for this kit is approximately +7-10% horsepower and +6-8% torque. Actual results depend on engine condition, supporting hardware, calibration, and testing method. On a mostly stock B18B1, the deeper induction sound and the low- and mid-RPM throttle feel are usually more noticeable than the peak horsepower number.

Q4: Will a cold air intake improve my MPG?

A4: Fuel economy is dominated by driving habits, load, and calibration. An intake alone can't guarantee a measurable MPG gain; the main benefits here are throttle response and intake tone rather than fuel economy.

Q5: Will this void my factory warranty?

A5: 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 a direct bolt-on that retains the factory MAF / IAT sensor location and bore.

Q6: Will it throw a check engine light?

A6: A correctly installed intake should not automatically trigger a CEL. Common causes after install are a loose coupler, an intake leak, a disconnected vacuum or breather hose, or a damaged IAT sensor wiring. Re-seat every connection and clear the code before replacing parts.

Q7: Do I need a tune after installing?

A7: No tune is required for a bolt-on install on a stock B18B1; the intake keeps the sensor in the OEM position and bore so the factory ECU stays within its calibration envelope. Tuning becomes more useful when you also add a header, full exhaust, intake manifold, cams, larger injectors, or forced induction.

Q8: How difficult is the cold air intake to install?

A8: The install is a direct bolt-on using basic hand tools. It generally involves removing the factory airbox and resonator, routing the aluminum pipe, reconnecting the vacuum and breather hoses, and mounting the cone filter securely in the available fender clearance.

Q9: How do I clean and re-use the dry cone air filter?

A9: Inspect the filter when dirt begins to collect between the pleats. Use a cleaning solution intended for dry cotton reusable filters, allow the media to dry completely, and reinstall dry. Do not apply filter oil to this media; this kit uses a dry cotton media that rinses clean without oil.

Q10: What does this intake sound like?

A10: You will hear a deeper, more aggressive induction sound under acceleration and at higher RPM; normal cruising should stay comparatively mild. Sound is subjective; if you want the loudest option, choose an open-element short ram style instead.

Q11: Is this intake safe in rain or deep water?

A11: Normal rain driving is fine when the cone filter is securely mounted and the factory splash shields and inner-fender liners are reinstalled. Avoid deep puddles, flooded roads, missing splash protection, and direct pressure-washing near the filter. A submerged open-element intake can hydrolock the engine and cause severe damage.

Q12: Does this fit a Honda Integra?

A12: The Integra sold in North America was badged only as an Acura, and this kit covers that Acura Integra LS / GS / RS with the 1.8L B18B1. The Japanese-market Honda Integra (DA/DC/DC2) is a separate vehicle with different chassis and engine-bay dimensions and is not covered by this kit. If you are shopping for an intake for a JDM Honda Integra, choose a kit specifically listed for that chassis.

Q13: Will this work with an aftermarket throttle body or turbo?

A13: This kit is engineered for the factory throttle-body bore. If you have installed an oversized throttle body or an aftermarket turbo / turbo inlet, verify the coupler size and pipe routing with our support team before ordering. Browse the rest of the intake lineup at the Flashark store.

Q14: What is included with the Integra cold air intake kit?

A14: The kit ships with one mandrel-bent black powder-coated aluminum intake pipe, one reusable dry cotton media cone air filter, and the silicone couplers, hose clamps, breather hose, and mounting hardware shown in the photos. The factory MAF and IAT sensors are reused from the original airbox (not included); basic hand tools are required for the install. Browse more intake options at the Flashark store.
