The 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 7-9 horsepower increase at the rear wheel, with no other modifications! Add a carb recalibration kit, a good performance exhaust system (not drag pipes) and a 12-14 horsepower increase is normal. Twist the throttle and watch the hotrod-styled vacuum-operated butterflies mesmerize onlookers.
