STC HPOP in late '04

Dene2006 · #1 (**permalink**) 02-23-2013, 05:11 PM

I'm in the middle of buying a few more parts to make my truck more reliable. One cheap mod to get that I read on these forums is an STC update kit, 4C3Z-9B246-F. Now I also read that in late '04, these trucks don't require one, (I'm pretty sure my ride is a late '04 version). Did I just waste $44 bones please?

Only 05+ pickups and late 05 excursions have the failure prone STC. The only way you would have one is if a later engine was installed.

Basically, if you have an aluminum HPOP cover, and an IPR that screws into the HPOP, then you've got an STC

Crap, didn't want to hear that, but thanks Matt.
