Owner reviews for spark plug

7751 are the OEM plugs and rated for ~105k miles, give or take.

I have only used Bosch plugs in my cars, and I have not had any issues with them yet.

I like my NGKs a lot. Never had any issues with them and they perform well

Honestly I think NGK plugs are better. Either one does the same thing, but I've never heard of a bad NGK plug, even well beyond its normal useful life.

Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.

Bosch iridiums, these for longevity, copper ones have better spark if your concern is performance

I stick with ngk iridium

The only thing I noticed when it was extremely hot and humid my car was slow in accelerating.

Those spark plugs are junk, and on top of that, they are now carbon fouled. I would strongly encourage you to install new, normal, spark plugs.

I’ve kept to stock plugs with stage 1. I tried the recommended “colder” plugs and they failed in less than 10k miles.
