Air intake backfire screen

I agree with No-Toil having issues in wet or hi humidity conditions. I quit using No-Toil after experiencing filter plugging during some 100% humidity rides. The filter already had some dirt on the outside surface and the No-Toil/dirt appeared to absorb the water vapor and turned the surface into to something that wouldn't pass air.

I have since switched to PJ1 spray or Belray. I think the No-Toil is good for dry condition and when cleaned often which is easy with the simple cleaning process.

As far as the flash screen, I figured the EFI system doesn't have a bowl of fuel to be blown out towards the filter. Just a theory.

I use PJ1 filter cleaner and Bel-Ray oil. Pulled out the screen in the air filter box. I don't think backfiring is a big problem with EFI.
