Do you guys know what plug are these for?
i just installed the some longtubes on my car and i dumped the egr stuff. as far as the Evap Purge solenoid. thing. dont -just leave it, and it does performance anywayz , (it only vents on partial throttle in drive) but under WOT, pcm stops modulating it, so it stops pumping fumes into the intake manifold.
