PAIR Valve

[gbpack89_imp]

No dirty air is injected into your engine. Go read how the PAIR VALVE works.

Yes, it is quite simple and effective; the additional oxygen completes the burn process in the exhaust header, cleaning up the exhaust emissions of hydrocarbons. Has nothing to do with particulates, that's a diesel thing. Nothing is sucked into the engine, it's clean air inducted into the header downstream of the exhaust valves. If it helps emissions why mess with it? Zero gain in performance.

This becomes an issue if you switch to a non stock muffler or open header
