Ive seen a few people say the 18 and up has the same opg that the gen 2 has. I just checked the ford catalog and ford uses a completely different part number for the gen 3 opg vs. the gen 2.
I would have thought they're on on their last leg due to how most cops drive those vehicles. They do idle extended periods but are usually to the floor also and driven hard.
While i'll be in the market for a mustang here in a few months, i had to join the forum after reading this entire build thread. Amazing! Love the car and color. Good work!!!
