I have a fully stock '03 kfx 400. I'm in the process of doing the "big 3" mods- full pipe, intake, jet kit. I purchased a full Yoshi exhaust off the internet and the jet kit at my local retailer. When I asked about a K&n filter my retailer asked if I wanted "just the K&N or the pro-flow kit?" The pro-flow is more expensive. I do plan to run with the airbox lid off but I really don't understand the difference between a straight K&N and a K&N with pro-flow. Could someone explain the difference? Do I need the pro-flow?
Thanks in advance,
