The airbox has cutouts allowing for additional flow paths directed away from the engine. This keeps air temps down, and increases sound without it being overbearing. The filter is massive as well. A big filter is desirable as increasing filtered surface area keeps the filter breathing easily for many miles as it filters dirt, dust, and particles. It measures 7" by 7" with a 5.5" frontal inlet, and a 4" outlet. The filter media is a washable pleated cotton gauze that can be cleaned for extended life, or replaced with ease.Our kit includes everything you need to bolt on and go. No new tuning is needed to run this product, and the product is emissions friendly. We include all new OEM gaskets and all the nuts, bolts, and clamps needed for an easy install. Lastly, thanks to our billet turbo inlet adapters, this is the only intake you'll ever need. Should you later upgrade your turbo, new, larger adapters can be installed to adapt to the larger inlets simply by swapping out the billet adapters!

About this Cold Air Intake

The APR CI100042 air intake system replaces the factory airbox and intake tube to let the engine breathe more freely. Intakes typically bring a sportier induction sound and can improve throttle response, especially on turbocharged engines.

Frequently asked questions

How much power does an intake add?

Gains vary with the engine and are usually modest on a stock car; turbocharged engines and cars with other modifications tend to benefit more. Many buyers choose an intake as much for the sound and response as for power.

Is this intake legal in California?

In California and states that follow its rules, an aftermarket intake must have a CARB Executive Order (EO) number for the specific vehicle to be street legal. Check the product details for an EO number before buying for road use in those states.

Will an intake cause a check-engine light?

A quality intake designed for your car should not. Problems usually come from a poorly sealed connection, a damaged sensor, or over-oiled filters contaminating the mass air flow sensor.

How do I maintain the filter?

Inspect it regularly. Reusable filters can be cleaned and, if they are oiled, re-oiled lightly using the maker's kit. Dry filters can be cleaned or replaced according to the maker's instructions.

How do I make sure this air intake system fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
