Perfect for 2018 suburban
Works perfectly for my 2018 suburban. It was recommended I use these since they run a bit cooler...I have performance headers, a tune, and a cat back installed. So far so good!

Improved Startability
Installed in a 2015 corvette with cam and supercharger. Car would have trouble starting from time to time - especially after short drives. This fixed the starting problem and improved my idle. I swear by these and also ran them in my big turbo Mustang Ecoboost.

Packaging issue
They are what I ordered and luckily came in undamaged. 4 were in a box and the other two singles were loose and came out of the box. They were at different places inside the package. Overall they worked fine.

These plugs are legit! Not fake China
These are Real NGK!!! Please for the love of anything you hold dearly to you. Do your research and don’t severely damage your engine buying knockoff spark plugs on eBay or elsewhere. I made the gable on eBay and tested them, also compared the boxing and labeling. The ones sold by this seller are legitimate and tested perfectly. They also come sealed with a verification label. I was very glad to see that. Highly recommend for your supercharged ford 6.2L engines. These are 1 step colder than factory for the added HP.

So far so good, these are NOT pre gapped, so make sure you gap them to your proper spec, but otherwise perfect for the tune on my Focus ST.
