Fiav Blockoff Plate

[Halon]

I have one as well from QPR. I did it for the simple fact that it eliminates a couple things from the equation, and no more idle surge. It does take the car a little while to warm up to idle right though, but doesn't bother me.

And the idle motor, it allows more or less air into the engine in certain situations. Like when you turn on the AC, it bogs down the engine a little, so the ISC opens up slightly more to allow more air into the engine at idle, so your RPM's stay at where you want them at idle. Mine is blocked off, so I set my idle to just shy of 1000k, so that way when I turn on the AC, it drops to right at like 750-800 RPM. That way I can run AC and not worry about the car dying on me.
