Alright so im about to hit 90k and figured i could use some new plugs and coil packs. Whats everyone running? Mods are in sig, im not gonna get real crazy with mods because i gotta save up some money for college and stuff. Anyone running Accel coil packs? Also how hard is it to change coil packs and plugs? Im fairly new to the 4.6, ive had a 5.0 for the past 4 years. And is this a pretty good deal? Summit 06-0009 - Summit® Ignition Tune-Up Kit Value Packs – SummitRacing.com

Thanks

I'm running the Accel COPs, and noticed a nice difference in the way it revved after installing them. It runs a bit smoother, and revs faster. I had a coil fail on me, and used that as an excuse for an upgrade. My car is a few over 90k as well, so I'd say a few of your coils are probably pretty tired, and you should notice a difference with those.

if im going to change the plugs i might as well go ahead and do the coil packs. i mean after 90k miles, whats it going to hurt, might as well do it right the first time around.

If you're going to swap out the COP's and Plugs, go with those accels but stay away from the NGK's. Get some original Motorcrafts, it's not uncommon for aftermarket plugs to shoot out of the heads.

Same here; I have TR6s in now. Ironically, it was the Motorcraft plugs that were starting to give me a problem in the past. They only had half the amount of threads on them compared to the fully threaded NGK ones. Nowadays Motorcraft (Autolite) plugs have threads down the whole thing, so it doesn't really matter.

-open hood
-remove connectiong from top of cop
-take a small socket wrench with a 7mm (i think not too sure) socket and losen the bolt fastening the cop into place
-remove cop with your hand. make sure to pull out the cop by its rubber boot.
-blow out plug well with compressed air to remove any and all debris
-remove spark plug
-replace spark plug to 22lbs/ft
-follow instructions bckwards, putting dielectric jelly on cop connection and tip of coil. also spray the outside of boot with some electric scilicone spray
-press cop back into place
-tighten bolt
-plug the electrical connection back onto boot with a little more dielectric jelly on the connector

this should take you the better part of an hour. you do NOT need to remove you fuel rails.

Its really not difficult, just a matter of having the right collection of sockets, extensions and elbows. You could probably do it under an hour easy...

You can get just the lower "boot/spring" section of the C.O.P. assemblies from O'Reillys Auto for $3.20 each. They slide right off. These lose their insulative properties over time just like a spark plug wire does.

There is no sense in replacing all (8) $76 each C.O.P. assemblies when the real culprit are just the boots.
