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.
