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
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.
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.
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.
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.
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.
