TGN has made an upgrade to the popular Short Stack Foam Filter; we have angled the neck on the short stack for easier access and more clearance for the fuel lines and throttle linkages. Include the TGN RedNeck Dual Stack Pre-Filter (Part Number 3228) for that extra protection. This product must be used with a velocity stack attachment. (TGN Part Number 3356) Short on space? Want a quality UNI foam filter? This one is for you. We believe this is the shortest filter on the market and it’s made just for TeamGoNads. The body of the filter is right at 1" deep. That's 2" less than the others we have seen on the market. This filter fits over any 1-3/4" velocity stack and holds on with the included hose clamp. Chrome cap and internal spring for added strength and rigidity make this one a winner!
