Carbon Fiber STI Fender Vent for the VA WRX and STI

The Compressive Tuning STI Fender Vent is a precision-crafted carbon fiber exterior accessory designed for the 2015-2021 Subaru STI and WRX. Developed and manufactured entirely in-house at Compressive Tuning, the vent replicates the STI fender vent aesthetic in carbon fiber construction for the VA platform builds that don't have the factory STI fender treatment.

In-House Carbon Development

Compressive Tuning's decision to develop and produce the fender vent entirely in-house ensures dimensional accuracy that generic carbon accessories cannot match. The vent fits the VA fender geometry precisely, with mounting that integrates cleanly without visible gaps or flex under normal driving conditions.

• Distinctive styling that enhances the vehicle's aggressive stance
• Integration potential with complementary aero parts like Airblades

Straight From Subispeed

For VA WRX builds that want the STI fender vent look in carbon, the Compressive Tuning piece is the correct approach -- in-house development means the fitment is actual fitment, not an approximation. A focused exterior upgrade that makes a visible difference to the side profile.
