DelphiGN10114 Ignition Coil

Work fine in my 2005 Trailblazer. I recommend this item.

I highly recommend these so far -1 month and working great. They are a moderate price, workmanship is twice as good as the cheap ones.. 2 years ago I replaced the coils with a cheap Chinese version. 2 years and 2 months later I had 3 fail. I had to pay for a computer diagnosis, because I thought it was something else. I replaced all of them along with the spark plugs (should be mandatory). The coils are easy to replace, but the spark plugs on number 1 and 2 cylinders are tough without a swiveling, thin walled 6"magnetic spark plug wrench. If you are going to change the plugs just buy the wrench, don't start he project without one. The first time I changed the coils and plugs without the proper tool I regretted it. Make sure you put anti-seize grease on the spark plug threads or you may never get them out again

Checked at our local parts chain store and the only replacement they had was an aftermarket coil pack forover twice the price. I was skeptical but very happy to get the authentic GM Delphi unit as I like to replace items like this with originals if at all possible. Unit fit and functioned perfectly as expected.

Arrived on time & was exactly as ordered

Great buy for a factory grade part

Replace bad coil ,works fine.

thanks

I have an old GMC Envoy SLT with the I-6 (4200 Vortec) that just won't die. This thing is as rock solid of a motor as they come. Unfortunately the coil packs occasionally go bad. These are excellent quality replacements. Started vehicle up, cleared the codes I was getting and she's purring like a kitten again. 150,000+ miles and she's still going strong.These match the OEM Coil Packs exactly. Don't buy anything else -- you really do get what you pay for. These are good quality. I wouldn't trust the reliability of my vehicle to cheap Chinese parts and neither should you.
