EGR Block Off Plate

I did some searching, I couldnt find much threads on it. I found an aftermarket one on ebay, for about 20 bucks.

Just curious if anyone knows about these and what kind of gains can be achieved. I heard that i might clean up your carbon deposits on your exhaust tip? idk.... What do you guys think?

i might sell my EGR block plate, not till after my euro-R is allready installed though.

its a 1/2 inch thick peice of alluminum.

came w/ my euro-R intake manifold..previous guy had an accord w/ a built NA engine.

SNslude is right though..all u gotta do is go to home depot..buy the 1 foot x 1 foot peice of thin alluminum, and then slip it through the EGR and cut around it.

Does blocking off the EGR affect gas mileage at all?

Nah, I don't think OBD1 cars throw codes on blocked off EGR's, I think OBD2 monitors flow or readings or somethin

No so much so that you would notice i'd assume. Basically all the EGR is for is for emission control (to reduce NOx iirc). It just recirculates your exhaust through your egr vlave and IM and back into the combustion chambers. So basically people block this off to basically cut this extra pathway off.

Yes they do throw a code unless you are lucky. I have removed mine completely and "faked" the computer into thinking it is working properly with some parts from radio shack

Oh, im part of the cardboard blockoff club too. hmm, i think mine was made from some Pot pies or something.

your actually only partially correct, and this is why i dont understand why people do this. The way the EGR reduces NOX is by allowing noncombustable gasses to enter the intake,, why would you want to do this? You produce NOX when combustion chamber temps get to high, so the inert gas is rentered into system to cut back on combustion temporarily to reduce these temps, and the funny part is the only time this occurs is when cruising down the highway at steady speeds...

I really don't want buildup in my intake manifold, and plenty of cars don't have an EGR valve in the first place.

what other block off plate mod are you talking about?
