Didn't say that we had the PZEVs, I said that the fiter is part of the PZEV emissions system, which is why it's big bucks. We use the same filter regardless.

If his gas mileage suddenly went south and there isn't a restriction in the airbox (indicator is in the green) and there isn't an issue with the stock exhaust, a new intake or exhaust won't fix the underlying problem.
