I don't usually write in to give my testimonials about thing I buy but in this case I find a need to say thank you to K&N for the Air Charger (air intake). I just had it installed on my totally stock '08 Road Glide. I'm not sure how much of any increase in horsepower it has actually produced but what I can tell you this from the first twist of the throttle I could notice and feel the extra power in the motor. Without changing anything else there is definitely a big difference in power.
Thanks again.

Best filters ever. Run them in all my vehicles including my Harley Davidson Motorcycle. Saved a ton of $$$ too by not having to purchase replacement paper filters every time.

All of my vehicles including my Harley Davidson have K&N Filters installed. They perform without equal.
