Engine starts better and in some cases the engine runs smoother. The big issue now a days is getting a legit NGK instead of a Chinese knockoff.

Pros: engine starts better

Cons: Chinese knockoff risk

I have a had a couple of NGK spark plugs with very fragile ceramic insulators over the last few years. I suspect like everybody else they are cutting on QC due to that inflation that officially doesn't exist, especially for made in Japan products.

Cons: fragile ceramic insulators
