Touch the button and your hawg turns into a wild boar. With a super strong bottom end, Harley engines can take more pushbutton horsepower than most. And, the fully adjustable Fogger lets you choose how much is just right. With the jets included in each Harley kit, you can expect to see a 30% to 40% increase in horsepower and torque. Plus, the Fogger can be adjusted for even more (or less) power by simply changing jets if your engine is modified. Easily installed in an afternoon, the Fogger kit comes complete with everything you need; including detailed, easy to follow instructions, nitrous and fuel solenoids, Fogger2 nozzles, filters, fittings, tubing, fuel pumps, T-fittings, jets, switch, hose, and all other hardware necessary for a complete installation. Please contact the NOS Technical Support Department for jet recommendations before you make any changes.
