The PERRIN Cold Air Intake with Heat Shield for the 2022–2025 Subaru WRX is engineered to deliver improved airflow, reduced heat soak, and consistent turbo performance on Subaru’s VB platform.

This intake system pulls cooler, denser air from outside the engine bay while the included heat shield helps isolate the intake from radiant engine heat. The result is more stable intake air temperatures, improved throttle response, and consistent power delivery during spirited driving compared to open or short ram intake designs.

Precision-formed intake tubing and a high-flow air filter work together to reduce airflow restriction while maintaining smooth, predictable airflow characteristics across the RPM range. The heat shield adds an extra layer of thermal protection, making this setup ideal for daily driving, stop-and-go traffic, and warmer climates.

Designed and tested by PERRIN Performance, this system offers OEM-quality fitment, clean engine bay aesthetics, and a refined induction sound that becomes more pronounced under boost without being harsh or intrusive. It’s a balanced upgrade built for drivers who want performance gains without compromising reliability.

Cold Air Intake + Heat Shield vs Open Intake

Cold Air Intake with Heat Shield

• Better thermal isolation from engine bay heat

• More consistent performance in traffic and warm conditions

• Balanced sound and drivability

• Ideal for daily-driven performance builds

Open / Short Ram Intake

• Higher intake air temperatures

• More heat soak during low-speed driving

• Louder sound with less consistency

If you want consistency without giving up sound, the heat-shielded setup wins.
