Overspeed Motorsports' injector seals will eliminate many issues relating to the failure of the factory injector seals. Whether you're trying to fix your failed, blown out factory seals or you want to reinforce the seal because of a high power applicatoin, or possibly both, these are for you. Loose and blown out injector seals can cause cylinder pressure to leak out through the injector area causing a loss of power, false knock from the seals moving around, and other issues. The problem needs to be addressed immediately if it's a problem and avoided if you're modifying. Overspeed seals are high quality and they're the last seals you'll ever need for your Mazdaspeed.
