Recommended coils and plugs

[Aspitler24]

I have searched and searched but I cannot seem to relocate the thread that had the info for recommended brand/type of coils and plugs. I know with some vehicles OEM only is a must, but I thought I read where a much cheaper kind on Amazon showed a lot of promise. If anyone knows what I’m referring to, any suggestions would be greatly appreciated.

Personally, oem plugs are my way to go.. cheap coils, this is what you’re looking for. I personally bought the triton V10 pack so I had a couple spares just in case, 2 years now and I still have those spares!!!

OEM for both and cry once. Aftermarket coils/COPs have always been shit for me, especially on Ford products.

Don't even think of changing a coil unless it's bad. Save your money. And if you can't afford OEM plugs, you probably can't afford a tank of gas to drive.

Have to agree with trainmaster, good to have a spare coil but no point in replacing as a maintenance item. Get my parts thru rock auto, use motorcraft plugs in mine.

I've spun wrenches for 40 or so. I've heard of coils getting weak over time. Expansion and contracting 1,000's of times tend to have a effect on things. I would have to agree personally. I know some will disagree but a very high percentage of people that replace plugs and coils at recommended intervals report getting 1-2.5 miles of fuel economy back. Mine currently is overdue for some maintenance. I know in my 01 Screw I went with street fighter COP's and NGK Iridium plugs and I haven't had any issues. I've always been one to change oil, plugs and such ahead of schedule because I tend to be hard on my vehicles. We spend money on upgrades and I for one want to get my moneys worth out of my Gibson exhaust. Here's a link to what I've found.. food for thought I guess.
