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).

Pros: engine ran smoother

Vehicle: Volkswagen

Replaced spark plugs on a 2009 Corolla 1.8L. I used NGK plugs, should I swap out to Denso?

when I worked for a Chevy dealer we hated Bosch plugs. Chevy's just don't seem to like them, they were often the culprit in misfire diagnosis.

Cons: often culprit in misfire

Vehicle: Chevrolet
