    Hello everyone, after having experienced many failures due to spark plugs and especially the NGK, it seems that the Denso are more reliable. What is your experience on this subject. I wonder if there are new generation spark plugs like iridium. Thank you

    I've not heard of many people having issues with the stock NGK plugs.
    I've been running the same set for a LONG time.
    We keep the same sparkplugs in our gasoline engine trucks for 100K miles plus..

    +1 Mike, NGK's never failed me. The expensive plugs making HP claims? I say, show me the dyno slip. They are longer lasting though. And, on marine use, we'd still take the Iridium plugs out every season and put something on the threads. That way the threads don't come out with the plug change in 5 years. Same with Mr. Max.

    Agree with the comments above, no issue with the NGK's.
