I am planning my tune up which I plan to do at the end of the month. What are the best plugs to get ? Also I may want to upgrade my coil packs , so any suggestions for those as well. I am running a 93octane performance tune in my truck right now so performance parts is what I am looking to accomplish the tune up with. Maybe some good quality injectors as well. Thanks for any advice

X2 on the plugs. The Motocraft sp-515 plugs are great. I went with ACCEL super coils vs OEMs. clean your MAF and throttle body too.

Motorcraft SP-515 Plugs, ACCEL coil packs here. I've ran em for almost 8-9k miles and no issues yet! Runs great!

What makes the ACCEL coil packs better than others? About to do my second and want the same things as the op.
