[FF1O5]

should i go with a regular k&n or the pro design pro flow kit?which is better?(400ex)on a stock 400ex and i will be jetting it and pipeing it also all at the same time.

If money is not a problem, I would go with the pro design kit. That would probably be safer filtering, and I think the K&N universial filter is larger so it will flow more air. I am giong to be purchasing one of these kits with the pro design adapter soon: http://www.btosports.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATV238107P&Category_Code=ATVIntake&Store_Code=BSOS
