Pre-filter or not on EFI 990

To pre-filter or not on EFI 2008 990 Adventure

Yes I have search and been reading about replacing the snorkel with a pre-filter. But have not been able to figure out the consequences to the A/F mix with EFI. I want to keep the bike stock only trying to protected the engine and give the air box filter a chance.

The story: Just disassembled the bike for the first valve check at 15,000. There is too much dust and grit in the air box and a little bit inside the fuel injector side of the air filter. The filter was dirty and obviously past due to be replaced. I did notice a loss of pep while passing at speed.

The question: If I run the pre-filter will I have adverse performance or loss of gas mileage? Or is it just plug and play and won't even know I have a pre-filter installed?

Thanks Knowledgably gurus of the air/fuel mystical world
