Technical Facts
Running factory power levels or seeking high HP numbers? Your fuel injectors work under extreme compression and combustion pressure. Don't let wasted power escape around that OEM excuse for a seal.
Seriously, have you seen an OEM injector seal? Throw it out now.
Get the GoSisteR Perfomance seal designed to deliver every horsepower to the ground where it belongs!
Our new, improved injector seals will keep you running longer and surpassing others. They are an extremely cost effective improvement, designed for 2006-2013 MZR DISI engines available in the Mazdaspeed 3 and Mazdaspeed 6.
Material: Reliable beryllium copper cups (1150MPa)
Superior design: 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.
No studs are necessary because the clamping force does not need to be increased above factory specifications.
