Fuel & Air

Not only do our Arlen Ness Big Sucker air cleaners look great, but they also increase air flow into your engine for better performance.

CV carburetors have become increasingly efficient and Ricky Bongos USA manufactures USA-made, CNC-machined carburetor tops to make them look as good as they perform. If you’re running a S&S Super E, B or G, we have some goodies for you, too. Clean up the bottom of your fuel tank by removing the petcock and putting on the carb. For Super E carbs only, these ON/OFF petcocks are a great addition to your S&S. They take the petcock from the underside of the tank and put it on the carb. For those of you that are true speed freaks and are constantly adjusting main and pilot jets, pick up a set of extended float bowl hardware. These little fasteners make changing jets a breeze. In the age of computers running and operating your engine, nothing can get the most out of your engine like tuning software. The pros at Vance & Hines have done it again with their FuelPak FP3 Autotuners. This is truly a plug ‘n play product for certain 2007-Present Harley Davidson motorcycles. Simply plug the FuelPak into your 4 or 6 pin connector, choose the performance parts you have installed, then choose the map you want to run. The best part is that it’s all done from your phone. It couldn’t be easier and you’re sure to feel the difference in the seat of your pants.
