ENA Set of 8 UF413 Ignition Coil with 8mm 748UU Spark Plug Wires Compatible with Cadillac Chevrolet Chevy GMC Canyon Tahoe LaCrosse Escalade Express Savana Silverado SSR Yukon CTS 4.8L 5.3L 6.0L 6.2L

Set feels like it's quality. Wires are decent.Installed with no issues on a 2014 Silverado 5.3I'm not sure I got the wire clips to "click" into place but it was cold and I couldn't feel my fingers enough to tell if that was a product problem or a me problem. Even if they don't click I wouldn't expect them to go anywhere.To remove the wires use a small screwdriver to pop up the red tab, then if it doesn't want to come off, gently pry the clip upwards, I use the handle end of my ratchet as it was a good fit.Random cylinder misfire gone! 👍Will update if they fail prematurely.

Received the coils today 1/11/23. Arrived a little earlier than expected and was packaged nicely. Foam inserts kept the coils safe and undamaged. Coils and included wires look great. Definitely higher quality than I expected. I chose the orange coils because Chevy.With 320k miles it’s not surprising that I had to replace a coil two years ago and just had a 2nd one go bad. I decided to order these to replace all of them at once. For $138 they are dramatically cheaper than $75 each for an oem AC Delco or Delphi.Got all 8 coils and wires installed in less than 45mins. Would’ve faster but the old wire boots were rotted and stuck on the plugs after only 3 years... Took the truck on a few test drives with some highway and stop and go traffic. it seems to be running smoother than it was. The misfire from the one bad coil is gone.I will be keeping the old coils just in case but fingers crossed I get some good use out of these. Will update as I put some mileage on them. I am very happy with my purchase.

Ordered these for my '11 denali. They were easy to install. Great quality and functionality form them. I wish there would have been a verity of colors to pick from. But what is most important I'd they fit well and work.

I've had these installed for several months now and they work perfectly. Perfect fit just like OEM.

had it for about two months. One of the wires broke but if you’re not planning on having to change them over to another vehicle and just leaving them on for the duration of the time then they’ll be fine. Boils work great good voltage no misfire only issue is the cheap wires. Just don’t unplug them once you plug them in and you’ll be good.

What a joke. Don't tell the buyer any real info on coils. Like how meany ohms,indution,spark duration,peak current max voltage. The buyer should compare them with this info. Don't buy them if they don't tell u these things.junk with in a short time I bet. And don't mention what they are made from either.

Great value

They do what they're supposed to do
