I have some spark plugs, 12, which I never put in my engines before I sold the rig. They are NGK 6993 BKR6EKU plugs which were inteded for my 2000 Yam HPDI 150’s. $5 each for all 12 and I will ship them to you at my cost. I will give you the fuel filter as well if you can use it and buy all 12 plugs.
The fuel filter is a 68F - 24563-00. make an offer.
Figure its a needle in a hay stack, but someone may need them.
