I have the stock sized K&N with no lid (secured the filter with some screws) and an outerwears cover.

Will I see enough of a difference to warrant the price of one of those aluminum airboxes or a pro-flo kit?

yes...the larger kn air filter allows more flow. Spend the extra $100 bucks and sell your stocker kn for $25 and get yourself the real deal....good luck,

Go with the pro-flow or equivalent. If you don't have the clamp on adapter, you need the lid. Even at best, the stock setup is crap and allows dirt/grit past the mating surfaces of the filter and airbox. The clamp on setup is the only way to go, wether you choose to run the lid or not.

What I did is I took the lid off and then sank a couple of sheet metal screws in from the outside of the box into the top edge of the filter, and put some grease on the mating surface of the filter... no dirt is getting in that way!!!

I guess I'm just concerned as to wether or not this filter has enough surface area to support a 686 build.

Just keep your eyes peeled on ebay or the classifieds here for a used one. You should be able to pick one up for no more than $50-$60 if you're patient. Lots easier to service and no need for grease.

BTW, what part of Northern Illinois are you in? I grew up north of Belvidere, but I live in God's country now. :thumbsup:

no, you wont get everything out of the 686 kit that you would with the clamp on style filter.

My dad worked in Rockford for years, at Sundstrand down on Harrison Ave. and Grandpa lived on Riverside right by Martin Park. Small world sometimes.

your most powerful setup would be no box at all. Aluminum airboxes are nice too if they dont restrict the flow too much.

I just cut my airbox down to literally the two supports, the part that connects to the adapter, and thats it... it works nice, the only difference i saw between this setup was increased airflow and i no longer had a box full of sand at the end of a ride...
