Great plugs when needing a colder option
Engine in my 2015 Mustang GT feels a little snappier, less knock under acceleration after installing the GT350 throttle body and cold air intake.

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!

C7 z06 one step colder plugs
This is for C7 Z06 - one step colder. Need to gap it. Good for bolt on mods or pulley change on Lt4 engine. I know Amazon says this doesn't fit but they're wrong. Also, they wanted me to use ltr5ix plugs which is 2 steps warmer and wrong.

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.

One step colder for Focus ST
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.
