Increase horsepower and style under your hood. The PERRIN Performance cold air intake system uses proper MAF alignment and plumbing size, which are crucial to maintain proper air fuel ratios and prevent check engine lights that plague competitors. With a PERRIN intake system your car will make a throaty, deep tone on throttle that is undeniably modified. You will be able to hear your turbo spooling and hear your blow off valve every time it opens. Even the stock one. Constructed from precision CNC mandrel bent aluminum tubing for consistent and perfect fitting parts. Their MAF sensor bung is CNC machined for perfect fit and alignment of MAF sensor to intake. This is crucial for proper air fuel ratios and ECU engine management.
