Description

The Cork Sport CST4 turbocharger is engineered to bridge the gap between stock and larger aftermarket turbos, offering a significant performance enhancement for the Mazdaspeed 3 and Mazdaspeed 6 platforms. It utilizes a modern forge-milled wheel, which provides higher boost thresholds, quicker response times, and increased overall efficiency for greater power output compared to traditional cast counterparts. This turbocharger is designed for direct fitment using the stock flange, allowing for boost to build by approximately 3500 RPM and delivering power up to 7000 RPM. It features an internal wastegate and a journal bearing for reliable operation. The CST4 is specifically compatible with the 2007-2013 Mazdaspeed 3 and the 2006-2007 Mazdaspeed 6 models.
