The PERRIN Short Ram Intake is designed to improve airflow, throttle response, and turbo sound while maintaining smooth drivability for Subaru WRX and STI models.

This intake system replaces the restrictive factory airbox with a high-flow intake tube and performance air filter, allowing the turbocharger to draw air more efficiently. The short ram design provides a direct, responsive airflow path that enhances throttle input and delivers quicker turbo spool.

Engineered and tested by PERRIN Performance, this intake system features precision-formed intake tubing and a reusable high-flow air filter designed for proper MAF scaling and consistent performance. The result is a sharper driving feel and a noticeably more aggressive induction sound under boost without sacrificing reliability.

The PERRIN Short Ram Intake is ideal for enthusiasts seeking a straightforward bolt-on upgrade that improves responsiveness and enhances turbo character.

Short Ram Intake vs Cold Air Intake

Short Ram Intake

• Faster turbo response feel

• Simpler installation

• Louder induction sound

• Compact engine bay fitment

Cold Air Intake

• Lower intake air temperatures

• Better consistency during extended high-load driving

• More complex installation

If you want quicker response and stronger turbo sound with easy installation, short ram is the move.
