Oi! I can start the car and move it out of the garage
But in all seriousness, the price of new Nissan coils are much cheaper than when I bought the Yellowjackets, so better off going for them. I think I got lucky with them, they held up fine at track days. But I haven't driven my car hard in a long time. Ignition is probably breaking down and I'm not noticing it haha. My car is also standard engine (standard ECU and ceramic turbos), so if you plan on running more turbo pressure, listen to these lot.
tl;dr buy Splitfire or genuine, unless you are poor and/or desperate.
