KIA/Hyundai 3.3TT Forged Race Piston

When it comes to piston design, why keep the stock emissions design? The GDI applications have "GDI domes" that are use to direct emissions safe designs, not enhanced performance. As I shared the design flaws of the OEM pistons (see FB post about the heat zones) we took that information, and made a proper forged design that enhances the performance, reduces the knock zones, has a proper boundary layer, and supports flame propagation across the whole piston, not just the interior dome. Welcome to the Tork Motorsports dedicated 3.3TT engine piston. Sticking with the stock compression we have redesigned the combustion shape/top of the piston, extended the ring gap spacing, and using thick wall tool steel pins with USA sourced ring packs... we have simply made the best piston available for your 3.3TT engine. What does all that mean? Stock compression works best with pump gas, but works even better with race or ethanol blended fuels. The compression top of the piston, in laymen's terms will not create knock zones like the stock pistons. The OEM piston is not for the performance minded enthusiast (yet companies continue to use the stock top design for their performance builds). Proper ring gap distances from the top of the piston allow for less heat, more seal, and better performance. Tool steel pins, simply put, nothing is stronger than this to attach the piston to the connecting rod. USA sourced ring packs... well, the USA facilities have been building rings for the last 100 years, that is 100 years of experience in building a ring for our pistons. Simply put, there is not a better piston on the market for your 3.3TT application.
