Do people want a filter that large for extended use... Cause I doubt the engine can flow as much air as that filter can....

Must be something like the large donaldson airfilter. But I do know of a ford owner who ran the air intake hose into the cab of his truck and hooked up a semi truck filter. The idea was to keep dust and water out of the intake.
The downside of it was, every time he floored it, his ears would pop.

The noise of that filter in the cab would be horible.... Just my AFE stage 2 intake has increased the noise outside the cab... the rumble, or low drone of that would drive most people nuts... and most would not drill a 4" hole in thier fire wall...LMAO...

I am also using a AFE
I've noticed no difference in noise or anything else. I'm going back to the stock or buying a AIS Severe Duty Filter. I noticed that one of our sponsors has them at a pretty good price. Just not sure yet. I"m sure as heck gonna grab one of those Cam Positioning Sensors he's got soon as I TELL my wife I want to order one.

You did not get a low rumble from the filter? There was no missing this... right out the front of the filter....

There isn't as much noise as a KN in the stock box nor nearly as much as a Scotty II with the hole drilled. It's about a $50 filter and a one time build of a heat gaurd between the filter and the turbo. Some in the wetter regions are putting a prefilter water resistant sock over it. Very cheap and effective mod plus no mess with cleaning and oiling.

I just put the afe progaurd 7 stage 1 on. I lets the turbo spool up faster. It also has a lifetime filter, and it filters more then a k&n does. It seem like maybe alittle more power as well.

You think that filters bad...oye...u shoulda heard my last rig...a BHAF, no silencer ring, 5 inch stacks, twin turbos....she could make some noise!...then again....

I'd disagree.
The BHAF flows about 350CFM, and the stocker flows about 250 CFM.
A CTD spinning 3200 rpm uses (359*3200/3456)= 332 CFM (assuming 100% VE)
But this is with NO boost! Add 28PSI of boost and the number goes up to:
996 CFM!
Still think you don't need high airflow on the intake??

Justin,
Where did you get the 350cfm for the BHAF? The BHAF has almost three times the surface area as the OEM filter, I have a hard time believing it flows less than 30% more.
These flow #s from a few old TDR threads seem to be fairly common.
the stocker flows between around 350 cfm @ 1.5"h20. compared to the afe mega force 850 cfm, afe progard 7 698 cfm, bhaf around upper 600ish cfm (all at 1.5" h20)

The info I have on the BHAF (AH19037) shows a flow rating of 687 cfm. But, the AFE Mega-Cannon has a flow rating of 820 cfm.

Part No. 19037 flows 915 CFM according to fleetguard.
(this may be a 4" h2o #?)
I found this searching for CFM ratings on TDR, I think it is the original BHAF thread.
Big Honkin Air Filter instaled

Strokin..Not ******
Yes....I HAVE a Tymar setup on my truck. All I did was take the stock airbox out. I used the existing intake hose and put a BIG air filter on the end of it. It site perfectly down in the well where the stock air box was. Funny thing, not really any extra noise.....EXCEPT the turbo! When I get on it good, I can REALLY hear the turbo whine. Fine with me!!!!! But, yeah, I do have the big ass air open air filter on my truck.....and I love it!!!!!!
