K&N for a 4af?

[SR5 Rolla]

Do they make a k&n filter for a 4af engine? Which store might carry it? Not alot of performance shops around here. Thanks. -Josh

For the stock 4AF "air box"? I know they do.. but what is the point?

[SR5 Rolla]

Because my fuckin air filter is dirty as shit...why else????

[|PuNiSh3R|]

Heh drop that carb and upgrade
And I used to run my stock carb with nothing on it but the open carb.. no filter or that cap..

Just go to autozone n get a filter for it.. no difference.. or put panti-hose over the carb..

[SR5 Rolla]

true, true. I probably am better off upgrading or taking it off. That thing is just so damn restricting. Kinda like tryin to breathe through a tube w/a rubber band around it..bigger carb it is then...wish i could make it fuel injected...

well, EFI is great if you want to drop a shitload of cash into it to get a GOOD programmable system.. I mean I've seen HIGHLY modified 4AG's running 50mpg on the high way because of a GOOD efi system that let the engine run really lean during cruise conditions.

If you want balls stuck to seat speed.. it's carbs. You can run a carburator to extremely high RPM's and not have to worry about mis-fires due to sloppy injection times because of the high rpm.

If u want my weber it's all yours.. I'll help you install everything.

Hey if you can gimmie a few weeks or so i'll buy it off of you. I'm in the process of gettin my car inspected. I had to gut my exhaust and do a few other minor things. So i'll be ready to roll soon. Thank god cuz i'm sick of drivin this f-150...

[|PuNiSh3R|]

what price?

[SR5 Rolla]

I don't know..Think about it and let me know. We'll work something out. I thought you love your webbers..What happened with them? Also did you notice an increase in power after installing? I heard motorcycle carbs work as well (certain ones anyway). -Josh

Actually the stock airfilter isnt that restrictive, its just a figment of imagination... running with an open intake will kill your engine very quickly and even faster if a rock or a bigger piece of debris goes through it... bye bye pistons and valves...

[|PuNiSh3R|]

It's good I never got rocks in my carb

Well, I installed the weber when I had my aftermarket exhaust and cams in.. so I can't really say what your stock gain will be.. I suspect that the primary jet in my weber was to small for my aftermarket exhaust and cams..

It comes with a K&N filter.. and bleh bleh bleh.. idk.. like 230?

[VooDoo]

have you tried routing a cone filter to your carb?

[SR5 Rolla]

Yeah would that work?? I mean taking out the carb filter, cut the tube that brings air in back a little bit, then put a cone filter on the end. Would that be pointless to do?

[|PuNiSh3R|]

Yes.. it would be absolutely pointless.. It would give you marginal gains but think of it this way.. the carb on that car is 28mm opening at the top.. for the primary and secondary.. I was running a 32/36 (32 prim and 36sec) Weber.. and now I have quad carbs which are 38mm each cylinder.. The carb on the 4AF is made for economy and nothing better.. so putting this filter on it or that filter whatever won't do shit.. I've tried a LOT of shit before I started my mods to make the thing faster and it just won't happen with that carb on there.
I even had a motor on the intake that is used for blowing up inflatable beds.. it's a strong motor considering it can inflate a bed with 230lb's laying on it.. (not me) and that didn't do jack.. I tried cold air intakes routed from the wheel well.. all kinds of stuff.. makes marginal difference.

[|PuNiSh3R|]

Oh, you could get rid of that carb and at the same time get the late model 4AFE head.. which has better porting for the intake so it has more performance already.. I think it's a late model 4AFE..

Anyway.. you can drop that head right into your block no issues.. everything bolts right back up and u can use your same cams etc etc..
