It's an R-Factory airbox originally designed for the S20 twin cam engine. I flipped it over and used it upside down on my L24. It has integral air horns welded to the base plate.

Short/medium height Mikuni-Solex/Weber type standard air horns would fit if you modified the base plate to accept them.

I thought it was rubber soul version which might be larger . I’d like to run 75mm horns but might be limited to 50mm . I’ll be running 45 ITBS . I still have my custom air box I might run . 
thanks
