Review on 🔥 Spectra Premium C-513 Coil on Plug: Revolutionizing Ignition Systems by William Stewart

I must report that these units failed together at 11,000 miles. I installed it on September 11, 2014 after purchasing it online. They worked for a while but about two weeks ago my car started to stall severely but intermittently. After taking it to the shop it became clear that I would have to replace one or all until the culprit was identified. Instead I replaced them all with my original OEM coil packs. They were fine when I replaced them but they went to 150,000. So I come here today to find out that a year warranty means nothing?
