I may be stating the obvious, but the only way to fix it may be to pull the blower for room and run a tap. I stripped the back two on the driver side and haven't fixed the threads yet. All i did was fill up the gap with about 2 or 3 washers to hold them tight. I used some RTV to hold them to the screw head while i put them in with a telescoping magnet. fyi. i ran it for almost 2k miles with the loose coilpacks and had no trouble. let me know what you do, hope i could help

After i stripped mine, it seems to have dug a new set of threads. I've checked the plugs 3 times and it always goes in the same way. Plus, you seem to get a better feel after fkng with them for awhile that you didn't have the first time around.

If the threads are totally shot you can use a small zip tie through the coilpack ear and the stripped hole. All you need is for the coilpack not to flop around any.

I snapped the #3 bolt after cross threading it and trying to tighten it down enough to make the coil pack seat. "One more 1/16 of a turn should do it" SNAP!!

I used metal dryer duct tape to wedge between the coil pack and the fuel rail. Works perfect. (Actually it does)

I have read so many tales of these coil pack screws.

I guess I got lucky when I checked mine but I was thinking of going to a specialty supplier and going with a stud instead of the bolt.

You could double nut the top and run the stud in tight, then just use a nut in the future. Less chance of striping the steel stud rather than the aluminum.
