kancil compressor no feeling wan wor for beetle..cause if u use kancil compressor..u gain a bit more of performance..but u dun get real air cond..real air cond by meaning cold air..actually..if u install air cond at 1.3..u can try to throw out all extra weight out..will somehow gain back a bit more performace..use a light alloy rim..smaller tire..back seat kasi buang..spare tire all buang..aam card give u better performance..
