If I had a choice between a resistor type NGK plug and a non-resistor Torch, I'd take the NGK in a heartbeat.
Laser iridium or ruthenium from ngk
Yeah, I use NGK laser iridium. I got a friend that has a m6, m5 v10, and uses those, it's good
Ngk's. First thing i did was get the original plugs out of my beamers and put in the ngk ones. Widely considered one of the best plugs for your engine.
Your misfire could be bad plugs, from looking at these pictures your plug gaps look massive. NGKs are good and motorcraft is also good and I wanna say cheaper from RockAuto.
NGK BKUR6ET-10, stock number 2397. With every other car I've owned, the first symptom of failing plugs is missing at higher rpms. In the AEG engine, the first symptom is that it gets hard to start. Do you find that too?
I literally JUST did this today to mine. used NGK 3967's (about $4.27 a piece)... And also replaced the spark plug wire for about $30 using NGK 4412.
I have the ruthenium. Bought pregapped from Mountune. They are fine. They work no noticable change. I've put about 200k miles on them between by ST and RS and changed every 50k miles with no issues (both tuned and stock).
My brand new out-the-box WEN 3500 would barely start until I tossed the Torch and replaced it with an NGK. It now runs as designed. Too many others have had similar issues and that's why Torch is widely regarded as junk.
Additionally I would endorse the use of a Champion or NGK plug. The LG/Torch/random Chinese plugs are a crap shoot. I see tons of failures on them as well.
