(8-Pack) NGK Spark Plugs LTR7IX-11 (Stock # 6510)

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

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!

Great price and product

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.

Worked for 2020 Tahoe

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.

My sons love these

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.

Very good product, very good price

2018 F150 Lariat 5.0L V8 works even tho Amazon lists it as not fitting this does work with that year an model truck no misfires no engine codes runs great real NGK plugs 10/10

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.

Not as expected

NGK are excellent performance spark plugs.
