    So I'm getting the feeling my stock ugly aircleaner is choking my engine a little. I dont like the idea of an open aircleaner in a mud truck ... so who makes the best flowing closed air cleaner?

    Make one yourself. First step is to yank that big permanent filter part out. Then grab a second air filter housing and graft a second snorkle on it...

    I wouldn't do an open element filter either. Too vulnerable IMO, although with snorkled intake it can be worse depending on where the outside airs enters. Some 9most) new vehicles have the intake up front and somewhat low making them prone to hydro-locking.

    That's what I would do too. It should be pretty easy, and is on my future plans list as well.

    Another reason to not use an open element type filter housing is you don't want to suck hot air from under the hood. The engine makes better use of the cool air being drawn in from the fender vs. sucking the hot air in the engine compartment.

    Some paper filter advertise that they flow better air than others. Of course there is also the whole K&N debate. It seems like I remember someone posting a list, or test, of paper filter flow rates... maybe a search here, or on google would tunr up something.

    I'm running the factory air cleaner off a '84 K5 with a 305. It's 5.5" tall and 14" in diameter and I use a 2 stage foam Amsoil filter. The only modification I made was to cut the "snorkel" off and make a matching hole on the other side for more flow. You could also easily route the intake into the cab, but the noise would be severely annoying.

    FWIW, that isn't a filter. It is an air straightener. It's purpose is to remove turbulent air flow thru the carb or tbi. I would NOT remove it. Think about it this way, some Engineer had a danged good reason to get that part approved by GM's bean counters. Turbulence is good in the combustion chamber, but not in the intake ports.

    I use the 3/4t-1t filter can that uses the tall filter element.

    A real air filter looks like one of these or these.

    I jerked mine out on my 84 w/ a 305 and it made a noticable difference on power. I guess mine was clogged up with junk over the years.


    My vote, would be to pull it.

    I was useing a dual snorkel corvette air cleaner. Now I use a nascar style. I had to cut onto the cowel it uses that as the air supply. Nice clean cool air. I even made a bale over it just incase mud or water splashes over the hood.

    when you say jerked, you mean to cut off the side snorkle and add another hole on the other side?

    No, the bean counters are why it didn't come with those stock. The engineers couldn't find a good enough reason.

    I switched from an open air cleaner to one of the tall factory air cleaners. First time I hit any mud I noticed that the front of the air cleaner housing was covered in mud, so I'm glad I switched.

    I did want some more air flow, so I drilled 3 holes about 1" diameter in the lid and I keep them towards the back so the mud can't get in.

    I think maybe you are mistaking the piece of metal that is tacked in right where the air comes in from the snorkel with the big wire screened filter that is glued to the filter housing.

    That filter has charcoal in it, it's all about emissions. Same thing as the EVAP cannister, only it's to try and retain the evaporated fuel from the carb from exiting the air inlet.

    Could be, but all two of them that I've looked at were only wire mesh. No charcoal in sight.
