Reviews of NGK spark plug

My grandfather use to say that Champion Spark plugs killed more American pilots in WW2 than the Japanese did. NGK for life.

I want to say that NGK is OE. Regardless, I got NGK and haven't been disappointed.

Just picked up another 4 Ruthiums from rock auto, can't beat $8 a plug.

Ngk are trash. Go with oem Bosch

Ill say this, i got a set of 6 high quality ngk platinun tips for like 60 bucks

I buy the NGK laser iridium spark plugs. About 100 dollars.

I decided to give the NGK Rutheniums a try earlier this year after reading about them on this thread I've been happy with them so far, the engine ran noticeably smoother than with the old plugs (but that could have also been simply due to new plugs).

I replaced mine last week and used anti-seize lightly. No problems that I see.

Replace the plugs with NGK or Denso.

I have the OEM RS7 plugs in my car for 40,000km ever since going to stage two with zero issues and will buy them again.
