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.

 An open element is much better.You might notice a slight differance on
the pedal,but don`t expect a lot.Maybe just a touch on the mpg.If your
looking for bigger gains,you'll need to do some motor work.

P.S. DON'T USE A K&N!!!!!!

How do you equate "much better" with "a slight difference"?

sort of a big picture small picture thing
much better air filter equates a slight difference in performance
sort of like what Bill said

 I guess I wasn`t thinking when I posted.
Pretty much the only way you will see any gains,would be on a dyno,or at
the race track.

unless you're willing to either drill an open air cleaner for the dual
studs, or fabricate an adapter to a single stud, then the answer is
no, nobody makes one.  if you're willing to do either step above, any
10" or 14" flat bottomed air cleaner will work w/ a 5 1/8" neck.
