AC Delco Ignition Coil D501C/BSC1508 (1)

Got these and after taking off the intake manifold they went in very easily. Will update after we get a few miles on them. They fit perfectly. I did notice the boot is just a smidge shorter than the originals.Torqued the bolt to 10lbs.

This ignition coil fit perfectly. The installation is fairly simple for anyone who has worked on car engines before. I have a 2009 CTS and had no issues. I checked the OBD codes before and after. Problem solved.

These coils cost little more than knockoffs. I would have gotten the knockoffs, but my mechanic said he'd recommend AC Delco, as he'd had some problem with others. These were less than 1/2 the cost of other OEM's I priced, and they work great.

Fit my 2008 Cadillac STS V6 and fixed the cylinder misfire I was having (also replaced spark plug). Inexpensive and easy to install, timely shipping, no complaints so far after a month+ of use.

The product itself was awesome. But the description was misleading. I bought the wrong part because there wasnt enough info for ordering. Shipping took forever.

Can't go wrong with a year warrantied factory OEM part. Don't go cheap, or you'll replace in less than a year.

Worked like a charm..hopefully it will remain working unlike the one it replaced (Only 3k miles before it quit), and was probably on average $50.00 less expensive for the same product on other sites.

Just what I needed. You have to check your Vin number to make sure you get the right one. There are 2 different ones for the CTS.
