The PERRIN Cold Air Intake is engineered to improve airflow efficiency, turbo response, and overall drivability for your Subaru WRX or STI. By drawing in cooler, denser air from outside the engine bay, this intake delivers noticeable gains in throttle response and mid-range performance while maintaining smooth, consistent power delivery.

Developed by PERRIN Performance, this system features a precision-formed intake tube paired with a high-flow air filter to reduce restriction and optimize airflow across the entire RPM range. The result is a sharper driving experience with an aggressive yet refined turbo induction sound.

Whether you’re daily driving or building toward higher power goals, this intake provides a solid foundation without compromising reliability.

Short Ram vs Cold Air Intake

Cold Air Intake (This Product)

• Pulls air from outside the engine bay

• Lower intake temperatures

• Better consistency during spirited driving

• Ideal for performance-focused builds

Short Ram Intake

• Pulls warmer air from engine bay

• Easier install, louder sound

• More heat soak in traffic or hot climates

If you want balanced power, consistency, and longevity, cold air wins. Period.
