Been running BUZHW in my 225 promax for years but I see they've discontinued them. Anybody know why? What is a good surface gap substitute for them? I thought about throwing some bu8h in there to see how it runs, but been told the Z resistor plug helps with RFI in the digital ECUs. I'm aware of the br8(9)hs-10 plugs guys like to run, but I like my surface gaps.
