Who has installed a catch can to their trucks?
It was mostly for fun, and I understand fully the dubious benefit(s) if any, but it is the only intake system I even considered purchasing. The trade off is the increased intake temps while sitting still, otherwise cruising temps average the same as with the OE intake (+10f over ambient). What I can say with certainty is, with that and the other changes I have made, my mileage averages 19+ consistently, and I'm positive I could do better if I could keep my foot out of it.Getting expensive!! Especially for unknown gains if any.
