They make block off plates for them. Buy one they are cheap. Or you could buy an updated intake manifold from a newer B18B1 and the EGR port wont be there.
it wont affect the fuel mileage as far as i know. Its an emissions component. If you are in a location which does emissions testing the dont remove as you will fail.
I know a guy who's an importer and can get one if he doesnt already have one. He can get you JDM front and a bunch of other JDM s*** if that tickles your fancy :lol: Hell he can get you an entire car if you paper is right. LEGALLY that is :lol:
how'd you get games? it took me straight there
