ACDelco Professional 9748UU Spark Plug Wire, Pack of 8

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.

great item also fits all 1999 and up gm

Quality AC Delco plug wires.

Parts were as described, for 2011 Silverado. Good value/ price.

You get what you expect from Delco products...

OEM fit

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!

Fit like a glove!

Work flawlessly can't beat oem

Great wires. Identical to the OEM wires that came on my 2011 GMC Sierra 5.3 L. Perfect fit and work great. Came on time and in good condition.

Fit my 2009 Sierra perfectly. Just remember to reuse the original aluminum heat shields from the old wires.

Works Great. Just like Oem. Price is fair. Recommended

Work like a charm...great price!!
