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.

Good find
Seals came fairly tarnished, however still a better investment over OEM seals for the same price. Noticeable difference in engine performance!

quality vs price
Over all these where a great product that greatly improved not only the potential of my speed 6 but the longevity of the injectors. the only down side is it is a bit pricey but for being specially made for this car it makes sense.
