great product especially at this price, fit tight on coils and plugs and immediately smoothed idle and driveability. scanned 5.3 chevy read random misfires on #7 and 8, checked wires for continuity swapped wires with #6 and 5, the misses moved to those cylinders so i knew i needed new wires. these came with a set of delco platinum plugs so since i have not changed plugs it was kind of a bonus at this price. the wires themselves are slightly long but not so much that they cause any problems, and look great. great deal highly recommend. the plugs were ac delco and strange thing one box had one plug that was NGK, wrong size. contacted amazon and they are sending out the one plug i was short.

Love the wires, heavy made. Put plugs and wires in Silverado yesterday morning. Runs great. Great value on order. Packed good and tight when shipped.

very good

I checked resistance on all of the items like I always do before installing any parts in any vehicle I work on; one spark plug wire was OL. Other than that issue, I like their performance. They are longer than stock like everyone was saying on the reviews, but that’s no issue.

Engine misfiring after 8,000 miles. Root cause - the spark plug gap increased from 0.032 to 0.075. The anode had dissolved. There was also a crack in the porcelain. This wear was typical for all 8 spark plugs. This product should not be marketed.

More bang for your buck always replace plug wires when you replace plugs cuz you'll need them

Wrong plugs wires work but plugs to shortly mechanic came to put them and he said they are not the plugs that fit my 2019five point v8 Silverado Chevy truck
