Great kit. A little expensive but its the lmm ast time you will need to repair your airbox. They improved it by getting rid of the bearings on each side. Not necessary and they were normally cooked by welding/brazing the flapper valve on the shaft. Now its a high temp bushing. Should have been designed this way in the first place.

A bit tricky to take the old shaft off of the butterfly. I took mine to a machine shop for disassembly. Watch the heat on installation. I used a HF flex core wielder on low heat wire speed 3. So far everything is OK. AMT IA
