Spark plug NGK or Champion
I run them. They are a good plug.
They are great. Also around 12k miles on mine - no issues.
Yeah I've had these on my 2010 for about 12k miles now. No issues, have been performing just fine.
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
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
Have them for 15,000 miles on these and frankly can't tell the difference from (spec. plug) with original that it replaced. Gas mileage is no better and no worse.
Well, shit. I just put new plugs in two months ago following what EQT recommended then! I didn’t know of these failures with projected tipped plugs. Guess I should have spent a little more and bought non projected at the time, dammit.
If these are for a TJ (97-05) return them and get NTK (NGK). The 4.0 will not like anything else.
