Perrin Subaru WRX (08-14) & STI (08-17) Cold Air Intake System

Increase horsepower and style under yPerrin's 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 yPerrin's car. Actual horsepower values will vary depending on other installed hardware, tunes, and overall condition of yPerrin's vehicle.

Precision Construction

Perrin's intakes are constructed from aluminum tubing, which is precision CNC mandrel bent, for consistent and perfectly fitting parts. Perrin's 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 yPerrin's turbo flat-4. Once installed, the sound of yPerrin's blowoff valve will be much more prominent, demanding attention and alerting people that yPerrin's car is undeniably modified.

T-Bolt Clamps

PERRIN cold air intake systems use high tech T-bolt clamps. Perrin's 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.
