Comes back to haunt ya! lol!

Will do. Is there any reason you prefer the champs over the NGK's?
Haunt me, yes. When I was a crew chief years ago, we had flightline FOD walks 3 times a day (once per shift over a 24-hour period every week.)

NGK is one of the most duplicated (copycatted) brands by the black market. Lots of info online about that. BPR4ES is what I believe is a "cold" plug as far as part numbers go. Is that the actual number this engine actually specifies?

I have always had better longevity out of Champion over the years in small V-twin engines.

I was engines. C-130 Well acquainted with FOD walks!

The BPR4es is a hotter plug than the Champion. It is what was originally installed when new.

Yes, both NGK BPR4ES. Single throat carb.

No FOD in the cooling fin area.
The NGK and Champion plugs listed are not the same. Physically, yes. Performance, no. Research it.
It is always best to stick with what the manufacturer recommends.
