after you get everything fixed don't run the oem plugs, they are too hot, if you want to run iridiums then get plugs that are 2 heat ranges colder and you'll be better off. you can also run copper plugs, i run ngk coppers that are 2 heat ranges colder and have had no issues at all.
I replaced my plugs with NGKs about 10k miles ago, I got them on amazon for about $12 a plug I think, engine runs great with them.
NGK BKR5E... Dual or single electrode, they both work well. These are the best plugs for these motors imo. They’re some of the cheapest as well.
I just installed STI plug wires and NGK spark plugs. After the install the car tried hard to turn over again but still gave me the same issue as before. Turns out the motor was not getting gas so I didn't need to get new plugs/wires, but I am glad I did because now my car doesn't idle weird anymore.
Car's is running smooth with the new wires and NGK spark plugs.
Ditch these plugs and pick up some NGK's gapped to .028 and your misfires should go away. If the misfires are still present, start looking over your coil harness with a fine tooth comb and look for any cracks.
Usually the rule of thumb i've seen is the more expensive plug you use in your vrt, the ****tier its gonna run. NGK BKR7E's gapped to .022 and mine runs grand.
Last night I finally decided to trash the bosch spark plugs and installed some new NGK spark plugs and while I had my upper intake manifold off I bought a couple cans of throttle body cleaner and gave my upper intake manifold out and also gave my throttle body a real good clean. It was covered in sludge. But anyways after I sea foamed it a couple weeks ago, changed the oil and filter, spark plugs and cleaned the throttle body last night my car is running like a champ and doesn't feel boggy anymore.
I have ran BKR8EIX and i noticed no diff switching to bkr7e.
I changed the plugs thinking that what it was. (it was not). I thought it was the coil packs so I bought a new set of four, which I have NOT installed yet.
