Here are some pictures of a bracket and heat shield I built for the new Amsoil eaAu4510 Filters. Everything is made of Cald Rolled Steel and the bracket is painted with high gloss black and the shield is painted with flat black high temp paint. The 4510 has a 4. 500 opening, so I cut my BHAF flange off and stuck it in the new filter and it sealed the gap between the filter and the 4" intake pipe. -Jason
