GB Manufacturing Injector Seal Kit - Mazdaspeed 3/6

GB Manufacturing Injector Seal Kit for the Mazdaspeed 3/6 includes the necessary o-rings and seals to properly reseal the injector, which is a recommended service any time you remove your injectors. 

Price includes 4 sets of fuel rail side seals, suitable for 4 Injectors.

OE Style Combustion Seals are included, but 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 so we highly recommend Overspeed combustion seals to eliminate these issues!

Add-ons for upgraded copper lower seals from Overspeed motorsports and MPS injector stud kits available to upgrade!
