Ordered two of these in case I had trouble with one. Took them to Ecuador where I am volunteering and BOTH DOA and of course now I can't return them. I had to put a 40 year old DelcoRemy back in my blazer to get it working and I'm not sure when I'll be stranded with it. DO NOT BUY THESE COILS! STAY WITH OEM OR RESPECTED POST PERFORMANCE COIL!
