OEM fit 2014 Yukon
This is a direct fit for 2014 GMC Yukon. It says they don’t fit but these are the oem fit wires for the round coils. Changed them and the plugs and they work great so far. Seem to be high quality like the oem ones.

Buy these and only these. Here's why:
Your 4.8, 5.3 and 6.0 are race engines. These engines rely on constant adjustments from multiple modules and sensors. The constants that the ECM relies upon are things like spark plug performance at exactly factory performance levels. Sure, some aftermarket plugs and wires perform just fine. But, in my book, why roll the dice. Also, do not discard nor damage the factory heat shields. They are reusable and very important if you want your new wires to last. Use a line pliers to grab the plug wire at the top of the boot and pry on the exhaust manifold after twisting the plug wire left to right and right to left a few times to help loosen the old wires. Last tip; buy a 1" extension OR put a socket on the back of your spark plug wrench if you want to change plug #8. Or...you will curse like a drunken sailor with terrets syndrome. Now, go bust some knuckles! ... show more
