Features

  • Delphi uses winding process techniques to control the length of wire between adjacent windings. Thats important because more length results in greater voltage differences, which in turn create more pressure that could break down the insulation and wire coating.
  • Delphi's ignition coils are engineered to Original Equipment specifications
  • Delphi's ignition coils are designed with proven materials, such as high quality wires and wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues
  • Epoxy vacuum techniques reduce air bubbles in the epoxy, because having fewer air bubbles increases the epoxy's insulation quality and reduces the chances of energy punch-through failures
  • Delphi's coils are designed and endurance tested to resist the common stresses that cause failure

Description

Delphi ignition coils are designed to operate as part of an integral engine management system to insert power into spark plugs and ensure fast starts, consistent engine performance and optimized fuel efficiency.

  • Solved My Cylinder Misfire Quickly & Easily
Size: Stock
Purchased these Delphi GN10571 pencil ignition coils for my 2012 Mini Cooper S after pulling a misfire and cylinder failure code. To confirm the issue, I swapped coil #1 with #2, and sure enough, the code followed—clear sign it was the coils. I bought the full set of six since it was a great deal and arrived next-day with Prime. I did check other sources like FCP Euro, which had a slightly lower price, but their shipping would’ve taken over a week. Local auto shops wanted $50–$70 per coil, so this was by far the most cost-effective option. Installation was very straightforward: unplug the electrical connector, then pull the coil straight out. Mine had likely never been changed before, so they were stubborn. Wiggling them gently back and forth while pulling made it much easier. I chose to replace all four coils at once rather than just the faulty one—better to do them all at the same time for consistency and peace of mind. After replacing, I cleared the codes, and no misfire codes have returned. My Mini is running smoothly again. Overall, this is a high-quality OEM part at an unbeatable price. If you’re chasing down a misfire, I highly recommend grabbing the full set and replacing them all at once. ... show more

  • Works for N52 BMW 328i
Size: Stock
Have a 2011 328i N52 that was pulsing rpm at idle and would cut power sometimes during acceleration. Took a look at the timing per cylinder and saw a degradation withing the ignition. I already had all 6 Delphi but that was at 100k miles. Currently at 160k miles and needed to replace. Car is running like new now. Delphi at this price cant be beat.

  • Looks like used with dirt on it
Size: Stock
The box looks old without seal, product not in a protect bag or wrap, the dirt on the product is original. I am not sure about the product itself as I do not feel comfortable to install it and never installed it. Follow up: I subsequently bought 6 more items hoping to get good ones, but they are the same: unprotected coil in boxes not sealed. I then realized they are just packaging issue, not used ones. I wipe out of the dir stuck on the rubber portion of the item, and installed them. The car runs fine, misfire stopped, so I upgraded the rating from one star to 4 stars leaving one star off for packaging. ... show more

  • Excellent quality and price
Size: Stock
Just installed them . They work wonderful. Same ones at auto zone were $50 more per ignition coil. I was a bit hesitant buying thru Amazon as some reviews indicated knock offs. The items received are exactly as described in fact are better than the original ignition coils that were in my car. Better quality and a perfect fit . So far my car has been purring like a cat with the new plugs and ignition coil . My car has 150k miles . Saved a lot of money doing this myself .. honestly an easy install. Going forward I will be buying all my auto parts online . You can’t beat the online price.. it’s literally the same item you will buy at a brick and mortar store. ... show more

  • Amazon is selling questionable items
Size: Stock
Do not buy from Amazon for this item. I attached a photo for comparison from one I bought from Amazon one I bought from an authorized seller. The the box of the one I bought from the authorized seller has very clear print. The one I bought from on Amazon, the print on the box are very vague.
