Aftermarket ignition coils.

Has anyone tried these aftermarket ignition coils? Do they last? Aftermarket in my area are around $80.00. eBay has them in a set of 6 for $83.00. My truck is an '02 SLT with about 140,000 miles. About 5 years ago I had to replace one because of a misfire and in a pinch picked up a used on. Worked fine.

A while ago I got a misfire back. Checked and there was another (different) coil dead. Put another used one in and still had a miss. Turns out it's a third original one dead. I'm wondering if the rest are going to fail soon and a whole set for under $100.00 looks inviting...

Any thoughts? Besides me being too cheap... :wink: I only use the Envoy for trips to work, about 1.5 miles mostly.

I've seen Standard brand fail early. Who knows with these CCC coils. It's ACDelco or Delphi for me (basically the same).

I too noticed the cheap $80 something set of 6 coils. I wouldn't waste my time or money personally but would love to know as well.

Take Moosemans advice and stick with those 2 brands OR since you only drive that truck to work, give the cheaper brand a shot and then come back to tell everyone here...

Well, I cheaped out and grabbed another used one. Took about 5 minutes to change (getting used to this now). Erased the codes and she started up and idled so smoothly... If another one dies I think I will look into some of those cheapies...

Mooseman mentioned AC Delco or Delphi. I thought those were the same thing. The three that failed on mine were all Delphi, and replaced with Delphi.

We used BWD coils on a friends TB years ago, probably has about 40k on them and they're still going strong as far as I know. Minus a misfire that developed from water seeping into Cylinder #4.

Delphi makes stuff. AC Delco doesn't really make the parts, they relabel certain parts, or use a supplier to build stuff to their spec. Delphi is a very common major GM parts supplier. AC Delco also uses some Denso stuff (like O2 sensors).

It's just if you lookup ACDelco and Delphi prices, you can pick the cheaper of the two. They are the same. In fact, if you look at the pics on RAm the ACDelco says Delphi on it.

I think Bosch was behind Delphi for supplying parts. Can't remember what it was, but one of the sensors I picked up for my Avalanche was a Delco but with a Bosch part number.

Everybody sleeps with everybody in auto parts. You don't know what you're getting anymore.

There exists a bit of dichotomy within the Made in China label. Everything used to be CCC in the early days because most items were manufactured without proper engineering controls, practices, etc. As the years have drifted by, there exist many legitimate manufacturers who partner with multinationals to produce any number of products which meet every quality standard one could expect. However, the quick, cheap, and dirty outfits still operate as well so for the time being there exists an increased element of risk with buying generic parts of that origin. It used to be the same way with Japan, and some day China will evolve beyond the junk peddlers.
