    This product is the best investment you can make on your truck! I have an 03 F150 Harley it's made a huge difference! The supercharger whine is much louder and there is a difference in performance. Go with JLT and you won't regret it!

    Called And had my new JLT in just two days. Got it on and went to the local 1/8th mile track in town and picked up 2 tenths instantly. no other mods on a 2002 harley davidson f-150,stock blower and pullies. Ran my best pass at 9.4 with just the CAI. Best on the market for sure, Remember, the truck weighs in at just under 7,000 pounds. Thanks for an awesome product and super customer service.
