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. These came securely packaged and were accurately gapped based on the GM recommendation of .040 inch. (I checked with a real tool.) 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. I'm guessing the 100,000 mile range for iridiums is a product of a lot of highway driving and not the mixed bag of back road short hops this poor truck has to deal with....
