I have a stock 1994 GMC K1500 350 TBI with stock air cleaner assy, dual studs for hold down and the plastic ring with hose connection for the crankcase ventilation connection on the top of the valve cover.
Question: Is there a replacement assembly made to replace the stock closed air cleaner assy with an open sided free flowing assy, to include the top cover with two holes for the hold down wingnuts? If so, can someone post a link? This would eliminate the air box et al.
Additionally, would having an open-sided cleaner with a decent paper filter element make much of a difference in mileage and HP?
Any info and advice is apprectiated.
Thanks. Andy
