🔌 Optimized for SEO: ACDelco Professional Spark Plug Wire Set 9726UU Review

I prefer to use AC DELCO parts whenever possible (although some are from CHINA). I ALWAYS use the black wires on my cars when making wire adjustments. Nothing says buff like ugly blue wires when you look under the hood :( Be careful to line up the wires as some are short some are long so you can go crazy!

If I had written a review a week after installing the cables I would have given 5 stars but after about 3000 miles I had a bad misfire and it turned out to be one of the new installed spark plugs. wires. All boots made good electrical contact with the coil and spark plug, but somehow the wire to spark plug 5 wasn't working properly. Boo on you, AC Delco

The seller sent me this exactly as promised but one of the wires had a broken pin and it wasn't discovered until we replaced the had finished work so we had to use one of the old wires to get the machine working. ACDelco is a great brand and I have a great history with them, just disappointed that it didn't work 100% for me. Worst of all it was my son's first car so I hated talking about ACDelco and then it happened.

2003 Montana was in need of repairs and the cables were gnawed by pack rats during storage. The wires on the motor were marked 1-6. Good. They don't, so I had to match and mark them with tape myself. They are NOT an exact replacement, so in some cases they were an inch longer or shorter than the original. Had to reset them after the job was done as some of the front wires were a little tight on the valve cover and you could smell them on the first ride. In general, they finally earned.
