I removed the stock air cleaner assembly off my '91 TBI 350. What do you guys use for "aftermaket filters". I really dont want to go with a cheapie chrome one, but it's looking like my only option without spending lots of $$ on one. Also, will I need a spacer or anything or will it just mount right up?

Thanks,
RG
 
what ever you do, stay away from a K&N if your offroading, they suck water up real quick
 
I just installed one of these. http://ramairbox.com/

I dicked around with a couple of other attempts short of it was I wanted a simpler cleaner setup. Found it on the net but the place is in my hometown coincidently so it allowed me to check out the stuff first hand which is always nice. Great workmanship, great guy, VERY knowledgeable, a little more costly than I had anticipated though.
 
Used an open element for a bit. It sucked in dust at too high of a rate and had to be cleaned/changed often. Went back to a stock setup, and the filter life has increased a whole bunch.

Honestly I'd have to check the cost, but it must have come in close to $240 with tubing and hardware and filter. Like I said the workmanship is great, fit is perfect.

As for a performance increase, after replacing a ridiculously clogged fuel filter, doing plugs, wires, cap and rotor, and replacing the clogged open air filter that came with the truck, this is the only thing that made a noticeable difference at the pedal.
 
For some reason, Ive noticed that TBIs are only happy with the stock configuartion. Everytime Ive seen one opened up, there is always some sort of hesitation. I had a K7N for a little while, didnt like the way it ran. Seems to run much smoother with the FRAM and original ducting. Im sure there is more power the other way, but I prefer it to be smooth.

I extended the hold-down stud and used the taller top from a one ton OE filter can. Doubled the height of the filter and kept the cold air plumbing.

My experience with K&N type filters is that they allow grit past them. Had one on my 'glass buggy and it always had grit stuck to the base of the filter. Tried greasing the gasket surfaces of the filter and It made no difference. Tried plugging the crankcase vent (the only port other than the carb opening) and that made no difference either.

I give K&N type filters a thumbs down.
