anyone tamper with theirs yet?

 

uh, why? they are there to make the car run better. egr gives cooler combustion temps. pcv removes condensation from the engine. dont mess with em.

 

um... let's see here... because they pollute the intake track... i wasn't saying delete them (this moreso applies to the pcv valve)... the main concern is EGR, since it pumps exhaust back in for "cleaner emissions."
