Reviews

ACE Performance from Tewksberry, MA
Fitment and detailed instructions were excellent. The R&D that has gone into this product as well as the support are second to none. We are proud to be a dealer and install center of these awesome products.

The sound of the airbox coupled with headers makes the GT3 RS sound incredible and the power gain throughout the RPM range is noticeable.
