I see this thread has gotten crazy!! I have an AB Mods JL. The thing is crazy fast!! Some people get modded engines, some don't. Its a matter of preference. I am going to eventually put my JL back in my buggy. Im sure you guys have been testing pipes, plugs, etc. I have the JP3 pipe ready for it. So what plug works best? Im going to have to spend an entire day with this engine to get it race tuned. It has very good potential, just a matter of finding the sweet spot!
