ACDelco GM Original Equipment 357A Ignition Coil Wire

Fit my 2010 silverado perfect. Fixed my issues right up! Super easy to hook up just plug and play. Absolutely wonderful. And cheaper then my auto store

I did a coil swap on a 2001 Corvette LS1 engine with D580 coils. The new valve covers used D510C coils. It was either new valve covers from Granatelli or bracket adapters that would not allow the oem plastic covers to be put back on. The new coils take the smaller coil wire plug so both harnesses were replaced with this part. I was able to place them where they looked almost like an oem finish. They work great and you really would have to try to put them in wrong. The second wire in the coil plug will be purple on #1 or #8. Always to your left when plugging them into the coils. The plugs pretty much hang right where they plug into the top of the coil. Hopefully will not need to purchase these again but I would if I do another similar project.

My 2011 Silverado WT had a Check Engine light with a "Misfire on Cylinder 2" code. I discovered an animal, likely a squirrel, had chewed through the ignition coil wire on Cylinder 2. Instead of trying to splice it, I just replaced the whole thing with this part. Took a minute to get everything else loose enough to remove, but after that it was a breeze to swap out. Works perfectly!

A little pricey but you get what you pay for. I like the plastic shroud to protect the wires. I zip tied it to my fuel rail and off to the races.

OEM A/C DELCO PART, Price was reasonable, part arrived on time, simple R&R, 2011 Chevy suburban 5.3, threw codes; P0300-00, P0353-00, along with a few others. Troubleshooting says #3 cylinder misfire, change #3 ignition coil. Changed ignition coil, cleared code, ran fine for a week then did it again. Changed same part, plus wires, plugs cleared code ran fine, again for a week. Happened again, changed coil harness, cleared codes runs like a champ! No issues. Tested the old harness with multi meter found a bad terminal. Other fixes said bad lifter never said anything about bad coil harness!

Those 15 year old , heat soaked , raggedy wires were causing a misfire . Replaced both coil harnesses and she’s purring better than ever

As described. Good quality, fit and worked with no issues

Install this product on my 2011 Camaro SS. Perfect fit and functions as intended.
