It keeps the black soot from building up in your intake...i cant remember the link but someone will post it there was a pic of what it looks like if you dont block it!!!! Also if you havent already done it you should change you turbo mouthpiece>>>lbz or the afe replacement
ok i got the blocker plate and im going to put it on in a few min. when the engine cools off. But i have been wondering.. Where does all the exhaust go that is being blocked off? just back into the exhaust or what? and all i have to do is slip the plate in right?
No cons that I know of. There is a possibility of codes showing up. They say that some trucks are different than others. I put one on my truck and to this day I have no codes. Have driven about 500-600 miles since the installation. I did notice that my truck smokes a good bit less. I don't know if it is just me or that the egr blocker plate keeps it cleaner.
