Coil Pack upgrade?

[trick76cj5]

Just a heads up, i just replaced 6 coils on my truck:
2 initially from Napa
4 from Rockauto

The napa units were OK, but not really that great.

The 4 Denso units I bought off Rock Auto were OEM Ford parts (with the ford information Dremeled off). Truck ran much smoother with these 4 . . . and the price is decent at like $75 each (compared to 95 ea for Motorcraft). I recommend going with the Denso's off RockAuto. The factory coils just work well, not much to improve upon.

Long story, but i got time.

Bought this truck from a dealer, it had a number of issues that needed fixed so i got a good deal on it. The previous owner is/was actually a member on here, so it was cool to see all the back story.

Anyway, dealer must have done the plugs, didnt' tighten them down, so i blew a plug out of the head and it took a coil. I replaced 2 coils and helicoilded the head . . .but i didn't trust the repair.

Found a 60k mile junkyard motor locally, so figured while stuffing that in, i would put on headers. Pulled the pan to check out the motor and it had Mahle forged rods and JE pistons (11.1:1), so now i had to do a really good job because this thing could actually make some power. Full gasket/seal kit, new trans t-stat gasket and fill, service all axles, and stuff a '19 t-case in it . . . it escalated quickly.

Coils seemed to all be working fine, except the 2 i replaced. Did new boots and resistors and found that 4 were totally rotten inside . . .so, seeing as i was already way more $ into this project than I told the wife i would be, I just replaced the 4 that were trash.

In teh near future, i will be getting 4 more . .. but now i'm buying a fuel pressure gauge since i don't think my fuel pump can keep up.

It always take some time to get a "new to me" vehicle up to *****. :-D
