  • Quality
Trucks running good now, easy install, and fit perfectly

  • Great brand and spark gaps were close right out of the box.
Quality parts and worth the money. Made my silverado run like new again. Gas milage I gained paid for the plugs. Exact fit for my 1500. Easy to install and better plugs hands down.

  • These are great plugs.
I worked on German cars for a long time and was a Bosch spark plug snob. Over that previous career I dropped in thouands. I'm coming around to NGK though. It started with the chainsaws and now, my 2014 Chevy Silverado with 5.3L V8. These plugs are a hassle to replace so I wanted make sure I got better plugs to avoid having to do it all over again.

Of course the engine runs noticeably better, the old plugs had 76,000 on them. I should have replaced the OEMs long ago considering the condition of the insulators on three of them.
