Review on 🔥 ENA Set of 8 Square Ignition Coil Pack: Compatible with Cadillac Chevy GMC Models - Avalanche, Silverado, Suburban, Tahoe, Topkick, Savanna, Sierra, Yukon - 4.8L, 5.3L, 6.0L, 8.1L - C1208 UF271 Replacement by Aaron Ward

Easy to install. Be careful NOT to order round coils for the Hummer H2, they will not fit. You need these square ones. So they looked ok after installation. Before that I changed the spark plugs and cables. But a few days later I started getting the check motor again and checked to see if it could be a bad coil from the new batch. So I have to order different ones and try to find the bad one in the 8 I replaced. After a long drive, the check engine light does not always come on. Sometimes it does, and it still works a little rough. So I have to spend more for original reels than these cheap ones I guess. While the price difference is huge, I'm trying to decide whether it's worth it or not because as I said, there's at least one bad one out of the box! So no, I don't really recommend them, but something in this price range probably does.
