Spark Plugs: What is everyone using?
 

I am running HP500 EFI's, what have people found to be the best plugs for these motors? Also are the Fram Fuel filters any good or should I be purchasing something else?

Thanks in advance for your advise.

Ngk and wix filters here

I only run NGK as well. I had autolites in my ski boat 2 years ago, and the entire porcelain blew out of the plug after only a few hours of running. Startled the crap out of up. I went right back to NGK's again after that.

BTW, don't get me started on the Champions........


Darrell.

NGK what numbers?..Wix fuel filter number? and where do you guys get cap rotor and wires want to tune mine up tomorrow before JAX this weekend.

NGK-BR6FS or AC-MR43T I prefer the NGK's

Nothin but NGK's Never ever had any issues

I agree on the NGK's.

You can find the Wix filters at O'reilly or use the Napa Gold filters. Either Napa or Oreillys can cross the numbers off of your old filter.

Thanks guys, I run the WIX oil Filters and I have NGK's in the boat now, just didn't know if there was something better out there. I'll get the WIX Fuel Filters as well.

NGK BR6FS....what gap?
