This my personal opinion from my motorcycle days as well as wave runners.

NGK NO GOOD KRUD

If I'm wrong please show me my errors. These plugs have caused me more trouble than the cheapest socalled American brand made.

I'm open to all ideqas of what plugs we should run in these rigs. We have been running iridium AC Delco and Champions.

But, on my 99 Silverado i went to 4 post Bosch iridium and could feel seat of the pants difference. Not great but, enough. I'm not do any plug chnages except when i start up on boost i will need to drop to a colder plug.

I would really like to here opinions on this from guys who are use to building power in late model rides. I know the iridium was designed to increase plug life. I could care less. I want the best firing without failure as i will most likely add a spark doubler kit just as I added the Keene Bell boost a pump kit to fine tune the fuel pressure once We have it at general numbers that it should be in. I will use A/F lights to jus watch fuel pressure guage and fine tune the lean out a tad more by looking at fuel pressure guage and lights.

So I'm just as interested in advice on plugs as this is something i have been lacking in checking up on and it is as important to the whole project as any of it is.
Thanks for all who help
