Yeah I've had these on my 2010 for about 12k miles now. No issues, have been performing just fine.
I bought these when I did my last tune up and plug swap just to try. I noticed zero difference in power or mpg.
Beware the spark plugs they sell are factory seconds I had top of the line ngk plug fail after only about 7500 miles
I used NGK at 100k miles and have been happy with them.
Skip the genuine spark plugs and just get NGKs. And skip the genuine oil change kit and get pentosin if you wanna stay oe
Yesterday my new Ariens made its maiden voyage up here in Maine and began misfiring under load. Called the dealer where I bought it and they said it may be the spark plug. Ariens apparently puts cheap Chinese plugs (Torch brand) in their machines. Long story short, new NGK and all is well. Powers through them berms like a pro.
7751 are the OEM plugs and rated for ~105k miles, give or take.
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.
