Enrita and a few other high WHP E9x guys have been testing them out, i'm not sure what they concluded about 'em.
Thanks. Yes,there is going to be a lot of researching to do.Leaning towards Burger's parts including the intercooler. The 1 is an awesome car, its very rewarding to drive. and yes they are the Okada coils, my mechanic tells me they do work,but they are really very expensive, but doing the basic math,if I have more fuel and exhaust flow in the engine,its only logical to have more spark,but I am no expert.
