on fuel injected cars...
Can anyone name some?
The breather filter I am referring to is part of the PCV:
Its on the LEFT of the pic on the LEFT cam cover.
The engines in question are modern MPFI OHC V8s that have a butt load of sensors and computer stuff.
So far I've heard that using a K&N breather will allow unmetered air to enter the engine (not good for OBD-II computers) as well as allow dirt into the engine DIRECTLY considering the age-old K&N vs Paper argument.
Then I've heard that its ok to use these becuase it doesn't matter if unmetered air enters the engine.
Modern MPFI engines normally use a tube that allows the crankcase to suck in air for the PCV system via the main air inlet tube - which means that the intake air has already been accounted for by the MAF.
