It was a real challenge developing new turbo intake hoses for the 991 Turbo. The lack of space made it really difficult to make a set of hoses that would outflow the stock plastic pipes. We succeeded but in some smaller areas we had to compromise and letting the hose have no clearance, so they will push or rub in some non-sensitive areas.

Porsche 911 turbo. This immortal icon. The absolute essence of the motorworld´s cars, the Porsche 911, elevated by ten – applied with turbo charging. Could it get any better for a car enthusiast? Rewarding through a sweeping bend, viperous in pooring rain, thrilling on full throttle, breathtaking on retardation.

About this Cold Air Intake

The do88 DO88-KIT179S 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.
