C.O.P's...

My car is at 131K and my coil on plugs look like theyre OEM. Im the second owner so no idea if they are original but they do look it. I'm not having any trouble with the car by the way, its running awesome and idles smooth with no misses at all, so the old if-it-aint-broke-then-dont-fix-it quote does apply here, but I had read that the original plugs were good for 100k or so, so I thought I might just change them out this week since Im already planning on doing some other stuff like changing my oil and filter, cleaning my CAI filter with my BBK filter cleaning kit, and whatever else I can mess with.

My question then is, if I do decide to upgrade them past OEM to something like Accel's Supers, should I do a re-tune after changing them out? Or would the small amount of extra HP they say their COPs give you would not be enough to have to worry about messing with my current tune?
Any info is appreciated.

You won't need a tune adjustment.

I am still of the "if it aint broke dont fix it" side of things. If the car starts missing and or is having idling issues, then I would see replacing them.

Also from some of the research Ive done, the Ford COPs actually produce more power consistently than the Accel replacements

Here is a quick COP how to if you get bored

If your dead set on replacing them try ROCKAUTO for some great pricing!

If youre wanting ford replacments at a good price, I believe there are a few EBAY sellers that are offering great pricing and lifetime warranties

PS I am full of useless information, ignore me if I overstep

As Jarrod said, don't waste you money on aftermarket coils. I have seen them cause more trouble than good. The stock coils are really good pieces. Change the plugs and look at the boots on the coils. If they look funky, change them. Most coil failures are caused by arcing to the head.

The cheapest I found OEMs for was like $75 or so apiece. X8 my eyes popped. One site I read that the dealership wanted $100 per. Wowow. The aftermarkets were all cheaper, except for the Granetelli's, so being the cheap basturd I am the cheap factor just got in my head and messed me up.

I may just take the advice here and remove them, clean the boots if needed, change out the plugs since thats the main part that needs changing when the car has gone over 100k miles anyways, and regrease them.

Thanx for all the info, very much appreciated.

Found these on Ebay $122 for all 8

Once again thanx for all the great info here.

I pulled each COP, one at a time, and actually they all looked pretty good so all I had to do was clean the boots, change out the plugs, regrease connections and plug threads, etc. Was a pretty easy and quick job.

Now. Pulling out and cleaning my BBK CAIs re-usable/re-washable filter was another matter. Cleaning and re-oiling the filter was as easy as when I clean/re-oil the K&N filters in the old skool air boxes on my other cars and 4x4s, but, the filter was a really tight fit in that panel hole and it didnt come back out so easy. I think I will order a new 2nd filter and the next change I do I will replace the original one I just cleaned/re-oiled with a new one, clean/re-oil the original then put it aside to keep for a backup. Just want to make sure I dont have a filter in there I might have damaged while getting back out of the hole. Plus I will always have another clean one to change out when its time.
