Overspeed Motorsports Injector Seals Mazdaspeed 3 2007-2013 | Mazdaspeed 6 2006-2007

Out of stock until mid-late January 2025

Overspeed Motorsports Mazdaspeed 3/6/CX-7 injector seals are hands down the best seals on the market. These seals have been tested in engines producing well above 700hp and unlike any other manufacturer on the market, can still boast a 100% success rate. These seals are machined in house at Overspeed Motorsports from high quality beryllium copper cups to allow proper crush sealing.

The groove and flared lip design allows the seal to crush into the cylinder head, sealing in the OEM location and against the side for superior sealing performance.
