Perrin Cold Air Intake - Fits Subaru STI 2008-2017 - WRX 2008-2014

Increase horsepower and style under your hood. Perrin Performance intake systems use proper MAF alignment and plumbing size, both of which are crucial to maintain proper air fuel ratios and prevent check engine lights that plague competitors. POWER Add 15-30 WHP to your car. Actual horsepower values will vary depending on other installed hardware, tunes, and overall condition of your vehicle. CARB APPROVED California and several other states have adopted an emission standard for the regulation of road vehicles created by the California Air Resource Board (CARB). This standard must be met and approved for a system to become CARB certified. When a system becomes approved by meeting the criteria laid out by CARB, it receives a unique identifier known as an EO number and is certified for legal road use. EO Number: D-735 PRECISION CONSTRUCTION Our intakes are constructed from aluminum tubing, which is precision CNC mandrel bent, for consistent and perfectly fitting parts. Our 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. FILTER TECH Dryflow filters provide the same level of protection as an oiled filter, but require less maintenance, are less of a mess, and have no risk of over-oiling. The rigid screen inside and around the filter media helps in preventing damage from debris and are ideal for dusty and rough driving conditions. AIR STRAIGHTENER The airflow straightener improves MAF readings by forcing incoming airflow into a uniform profile. Smooth and predictable airflow is the key to good, consistent MAF sensor readings for reliable horsepower gains. SOUND During normal driving, the PERRIN intake sounds relatively stock. However, under load it really comes to life, unlocking the sound of your turbo flat-4. Once installed, the sound of your blowoff valve will be much more prominent, demanding attention and alerting people that your car is undeniably modified. T-BOLT CLAMPS PERRIN cold air intake systems use high tech T-bolt clamps. Our high end clamps offer maximum holding power and have a built in liner so they will not damage silicone couplers. Each clamp is stamped with the PERRIN logo. FINISH Powder coated for protection against the elements, the textured finish will look awesome for years to come. The PERRIN WRX/STI Cold Air Intake is available in black or red wrinkle powder coating. 5 Year Warranty PERRIN Performance warrants to the original purchaser that all PERRIN products will be free from defects in material and workmanship within a sixty (60) month period from the date of purchase. *Some exclusions apply » Read Full Warranty Brand: Perrin Carb Exempt: Yes Carb E.O.
