Fits All HEMI V8 Engines .. Excellent Performance
I installed these spark plugs on my Dodge Durango 2015 V8 5.7L (GCC specs), and the performance is outstanding. They are a perfect match to the factory plugs, but the results are even better. Fuel consumption has noticeably improved, acceleration feels stronger, and the engine starts up smoothly every time. Overall, the driving experience is more powerful and responsive compared to the OEM plugs.Highly recommended

Good quality
Worked well in my 2021 dodge ram warlock. Each plug was gapped properly and I had no trouble with the plugs, and they are working as expected. The work to replace them is challenging, but doable if you take your time, and lots of breaks. A swivel plug socket is very important before you start to replace them.
