Best of the best of best Sir! …With Honors.Great brand quality, fit, function, and performance. - You DO need to set the gap on these to your specifications. (I.e. .040 for Chevy 5.3L LS Gen IV) but if you are changing only every 100K miles, then no big deal. If you don’t know how to gap a spark plug you probably shouldn’t be doing this yourself anyway…

Ordered the wrong size since I was a year off on my vehicle. Called the company and they exchanged no problem. Great service! Plugs work great and were gapped appropriately.
