Kuryakyn's Hypercharger set the standard over 20 years ago as the benchmark in V-twin performance. Normally, replacing a stock air cleaner with a Hypercharger will net you a 7-9hp increase at the rear wheel, with no other modifications! Add a carb recalibration kit, a good performance exhaust system (not drag pipes) and a 12-14hp increase is normal. Twist the throttle and watch the hotrod-styled vacuum-operated butterflies mesmerize onlookers. Includes lifetime washable K&N filter element. Adjusted fuel control is required when installed with non-O.E.M. Kit contains an all chrome Hypercharger, mounting kit, K&N filter element and jetting necessary for carbureted models for complete installation. Black
