which air cleaners?

Posted August 9, 200420 yr

i'm debating on which air cleaners to get for my SUs... right now i'm torn between the K&N round assemblies (similar to the ones in the second link) and the ramflo/longflow style air cleaners that MSA and victoria british sell... i plan on using MSAs air horns on my carbs to optimize flow efficency as wel. i was pretty much set on the ramflo ones but then i read on hybridz that if the intake backfires it will melt the air filter element (that wouldn't be too yummy). i plan on purchasing these very soon so any input would be great!

ps.... since the ramflos will save me a little $$, they are a little more attractive...

I think you will get better filter protection from the K&Ns. I like the K&Ns.

I not certain, but I think the K&N's are 3'' deep and work better with the air horns, allowing you to get the full benefit of the horns.

Don't quote me, There are far greater experts out there than little ol me.

Why not just buy a K&N filter for the stock Air Cleaner Assembly? Then you don't have to figure out plumbing places for the Float Bowl vent hoses, and the the Flow Guide Valve.

Can't go wrong with the setup from ITG...MA sells them, large air volume good flow. Little $$$ but worth it. I've seen only 2.5-3 HP lost on RW DYNO :devious:

because the stock air cleaner doesn't flow well enough for me, and i don't want to cut holes in it since i don't plan on butchering it. also, the winter/summer flap keeps closing on me when i'm driving and it gets me al hot and bothered....

the ITG looks ok, but i'm afraid that it might have the same effect if my intake backfires. also, i don't believe that it filters as well....

Anything you put on the car to replace the stock air cleaner will flow WORSE without Air Horns. Don't believe me? Talk to ZTherapy!

Jason,

I've seen the foam burn, but only under odd ball circumstances..

Fellow racer lost his altenator, and battery lost power, causing misfiring engine, did catch on fire and burn big spot in the hood.

Proper running car shouldn't have that kinda flame. :classic:

The element is 2 stage on ITG, with proper oiling , I've had no filtration or lack of filtering problems....

Yea I second that,

Without stock horns, you will gain a couple HP up top, but torque curve drops way off.

Those MA horns look awesome...I may have to give em a try.

I had some cheap air tubes on and after I replaced them with those full radius (MSA ones), I did see some smoother running difference and power gains too (but not more than a couple HP). The K&Ns are probably more durable but they are a tight fit to get on between the air horns and in inner fender wall, but you can do it. I have mine off & on often and hate fighting with them. I usually make Mrs. Chino do it, she has more patience with them than I do. Regarding the fuel bowl vent, you could put a nipple fitting on the K&N backing plate, or route it to a small inline filter or into a seperate overflow canister. But don't cap it or restrict its free air flow.

Good luck.
