Yamaha genuine Spark Plug

[harry25175]

Hi,
i was wondering, how does the genuine Yamaha spark plug differ with normal NGk spark plug?

Some told me that Genuine Yamaha Spark plug last 3-4x longer than ordinary NGK. However, i notice that genuine yamaha spark plug is also made by NGK, so any different???

thanks

Yamaha uses NGK plugs, they don't manufacture their own spark plugs.

My Yamaha 90HP came with NGK spark plugs in 1999, still running the original plugs, so they don't really wear out, just get oily/carbon, etc. Keep them clean and they'll last a long time. I use a Harbor Freight spark plug sand blaster($15), never buy plugs for outboards, mowers, blowers, etc., just clean carbon off and re-use them. So far, so good!
