Under your hood, increase power and style. In order to maintain optimum air-fuel ratios and avoid competitors' troublesome check engine lights, the PERRIN Cold Air Intake (CAI) system uses proper MAF alignment and tubing size.

Add 10 WHP to your car! Actual horsepower values will vary depending on other installed hardware, tunes, and the overall condition of your vehicle. Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required. However, more power can be gained with proper ECU tuning! Our intakes are constructed from aluminum tubing which is a precision CNC mandrel bent for consistent and perfect fitting parts. Our MAF sensor bung is CNC machined for perfect fit and alignment of the MAF sensor to intake. This is crucial for proper air fuel ratios and ECU engine management. With a PERRIN Cold Air Intake system, your car will make a throaty, deep tone on the 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.

This PERRIN product features a durable powder coat finish. PERRIN powder coating is available in either red or black and is accented with a wrinkled texture finish. PERRIN Intake filter elements use open cell foam to capture dust and dirt. Washable and reusable, PERRIN Foam Filter elements can last the life of your vehicle. Foam filter elements offer superior performance with minimal airflow restriction and amazing dust-holding capacity.
