Show original supplier description
The Perrin Performance PSP-INT-301 Cold Air Intake System is engineered to enhance both the performance and aesthetics of your Subaru's engine bay. This system aims to boost horsepower and improve engine response by allowing for increased airflow, while its precision construction and available color options add under-hood style. This precise calibration is critical for maintaining correct air-fuel ratios and preventing "check engine" lights, a common issue with less sophisticated intake systems. The system utilizes special silicone clamps with a built-in liner to protect the silicone couplers from damage. The Perrin PSP-INT-301 intake is available in a wrinkle-finish powder coat to complement your STI's intake manifold or PERRIN Front Mount Intercooler tubes, with choices of red, black, and silver. The included reusable foam air filter elements capture dust and dirt effectively, offering superior performance for turbocharged vehicles with minimal airflow restriction and high dust-holding capacity, thus increasing turbo longevity. Box contents include the Perrin MAF adapter, cold air extension, foam air filter, silicone couplers, all necessary hardware, and instructions. This cold air intake system is specifically designed for the 2002-2007 Subaru WRX and the 2004-2007 Subaru STI. Perrin Performance backs this product with a 5-year warranty.
