helps u fail emmissions.

egr block off plate prevents the exhaust from going back into the intake system. The egr stands for exhaust gas recirculation. Yea, if u didn't know beforehand...some of your exhaust gases get re-routed back into the intake manifold for emissions purposes. The exhaust gas is inert(since its already been combusted) and since inert gases don't burn it just takes up space in the combustion chambers. The egr valve only opens during cruising though and helps with gas economy i believe. It reduces c02 or no2 whatever the hell is in exhaust gases. It isn't open at WOT. Most ppl, like myself, just do the block off to prevent the intake manifold from getting dirty. No need to buy one of those plates tho. Just simply take off your egr valve, trace the bottom of it and then cut that figure out on a thin sheet of aluminum. Took me all of like 10 minutes...added some rtv sealant to seal the plate in tho. Hope this helped

p.s. not a wise mod if u have strict emissions laws

Is your car permanently throwing a CEL code, or have you done something to the ECU?

no CEL's, nothing done that had to do with the ecu. Disconnecting the egr is the only thing that throws a code. Stick the block-off in and it thinks its still doing its job with no probs
