Air filter Q, Please enlighten me!!!

[bryguy]

I have the solid MAF tube & K&N filter which my Mech said is causing great turbulence (He has #'s from track). I can't move my gas overflow???round tank to the frame (usual mod to fix this) cause the previous owner put a tie down or come along strap on. SORRY My Q is can I ditch the Giant filter for one half as long with an opening in the front as well as the sides....You know the kind you find on Civics?@@#%!! anyway would I lose HP & has anyone done this or have a good answer....Thanks in advance

The filter you need is a K&N #RX-4150 filter length is 4-1/8in base is 5-3/4in top is 4inch & the mounting flange is 3-1/8 in ID the clamp will take up the extra 1/8in.

your mechanic is full of baloney....it is true than any non stock air flow ahead of the maf will disturb maf values....but, certainly not to the detriment of performance!

you put a smaller filter on, you flow less air....period

Sorry forgot the top is the Xstream air flow top and the part# above is wrong the correct# is RX3950 same dimensions as above

Here are other (probably better) options.

Put the air filter behind the headlight like I did. Maybe $25 in parts, tops. Colder air and no worries.

BTW, your mechanic is full of doo. You could have problems if you remove both MAF screens, but otherwise no prob.

I changed from a Kenne Bell 9" filter to a S&B 7 big mouth" filter with better results. I say thumbs up to the S&B. Then again I have nothing against K&N>

Also Kenne Bell said their 9" filter was good for 800 cfm. S&B says their 7" is good for over 1200 cfm. Maybe thats why K&N now offers a style like the S&B.

The biggest restriction to flow of most airfilters isn't the size of the element, but the transition into the hole. A 14" filter with a square sided transition will flow measurably less than a 6" filter with a bellmouthed transition.

The smaller the outlet diameter, the bigger the difference. This is why ricers were the first to embrace the properly bell mouthed filter. With a only a 2.5" outlet, a bellmouth can greatly improve the flow potential.
