I received mine yesterday & installed this morning. I had to clearance the mounting bracket to keep it away from a wire bundle & the engine. Compared to my previous 3" custom intake tube, it looks better, but Virtual Dyno results aren't better. I'll clear KAM and try again in a few days. Air Mass and Air Filter Pressure are similar to my 3" intake tube. CAT is similar to before, Intake temp is higher, but I had to remove my custom lower box to make the green filter fit.
