Can anyone give me some good ideas (in order of importance) of what I can do to my 03 Sportsman 500 to give it more HP and torque. Thanks

 

K&N with Outerwears to let it breath. Then get a clutch kit to get the power to the ground better. If you want more then throw a pipe on there. Heelclicker is suppose to be a really good kit for the utes. Look to HPD, RCR, AAEN, or HSP for performance products
