NGK 95399 SILMAR9B9 Laser Iridium Plug - Item# NGK95399
I have ran those for about 1,000 miles or more now
what spark plug wrench did you use? i don't know which one to buy because of the length.
I’ll chime in on this one. I noticed no performance gain on the butt dyno. Where I did notice improvement is them holding up to my excessively rich fuel map without needing to be pulled and cleaned constantly. I don’t think anyone has pushed the limits of the ignition system where this is relevant yet, but there is also something to be said about using a higher reliability plug, even in daily driving conditions.any difference running these iridium plugs? would you recommend buying these instead of the stock ones?
yes I also second rkturbo's reply, as well as what he said, they should operate at peak performance for a much longer time than the standard plugs( so rather than 10k miles lasting 20k, 30k or however long...I know in your average street car they are 100k mile plugs, so I would probably say doubling the average plugs, so 20-25k seems right...could be longer)any difference running these iridium plugs? would you recommend buying these instead of the stock ones?
