THE standard for Japanese automakers. NGK are high quality. Period. Bonus if you get them on sale :)

The gap of these are accurate and at 0.035. It also took away my misfiring at high RPMs due to running weaker/oem gapped plugs. Performance is great and I still get good fuel economy on them.

as always NGK proves to be an amazing company. i wasn't sure what plugs i should run for my new engine build at the power/boost level i plan to be at. a quick email to the folks at NGK and they replied within an hour with recommendations, explanations, part #'s, etc.. i've never had issues with their plugs and their customer service is outstanding. top quality parts from a top quality company.
