2015 GMC Yukon with Square Style Coil 17 Piece Performance Ignition Kit TRQ Performance TKA06356

These coils and plugs work great! No issues at all and definitely feel a little more power. Highly recommend!

Everything fit perfectly, Good quality products. Basically OEM, but a little better. Happy with my purchase!

Everything was great got my purchase fast it all went on good the only thing was had a defective sparkplug that kept throwing a misfire code but I changed it out and all good didn't bother calling to to complain didn't see that it was worth the trouble bought another plug and all good

1A Auto was incredible to work with. Superfast shipping and handled my refund quickly and professionally. A refund of $32. for the 8 plugs. I was very happy with the TRQ kit I purchased until my car developed a miss. And of course it happened on the day I was taking the car to get dynotuned. Come to find out 4 of the 8 brand new packaged plugged were bad. Yes, I should've checked the gap before i installed them. But they come individually boxed and sealed & then wrapped in a casing that says "do not gap". 2 of them were pretty much smashed all the way closed. So on top of this kit it cost me an additional $259. to get 8 new plugs and installation by the mechanic at the high performance shop. Very happy with the coil packs and wires. Just check the gaps on the plugs if you should get this kit.
