Perrin Cold Air Intake Subaru Impreza WRX/STI 08-14 (Red)

Precision Construction
Perrin Performance 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. PERRIN cold air intake systems use high tech T-bolt clamps. The 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.
