Title says it all, SU Air Filter Set 650-275. They drilled the air filter cap to bolt vertically with the dashpot and it interferes with the backing plate. On top of that, it fits so poorly as to cause the backing plate to bow from the interference of the screw head on the dashpot. There's a 1/16th inch gap between the carb throat and backing plate, they said add a few more gaskets :angry: Guess what happens when the gaskets deteriorate and a bolt comes out inside the filter? And how do you get a tool to the top bolt without removing the dashpot? Its a phillips head btw. They won't stand behind their products, last purchase I'll make from them.. Thought I'd let ya'll know, these are priced at 60 bucks buyer beware. Here is the k&n version showing the bolts holes horizontally for attaching the filter tops.
