$539.95 for an Air Filter??!!

[Gary - K7GLD]

What's Really going on here??



BUT! Documented Test Results are as follows:



12. 5 mile drive home from work during rush hour traffic (highway driving):



Amsoil 4510 used BHAF style = 55-70 minutes

PSM Stock Sealed Airbox Mod = 55-70 minutes



I am ok with these results because this is what was basically claimed in the recent TDR Mag article that showed dyno results under different "Real Life" conditions. Since the bottom line indicated in the article was this setup starts to shine while pulling heavy on hot summer days, I'm going to start pulling my 28' 5th wheeler to work and back starting in June. . Oo.

Not sure what the meaning is of your "test results"?



Are you saying it still takes the same amount of time to/from work, in driving time, with both setups?



Just joking perhaps?



USUALLY, the focus in comparing air filter setups in relation to outside air, is reduction in intake tract temperature, as well as improvement in total flow rates, power improvement, and general durability/lifespan of the filter media.



What type filter medial are you using? When my OEM filter setup became too inefficient, I went to a drilled airbox and K&N filter - and eventually went to the BHAF, then the 4510, after added mods - but NONE of those changes affected my driving time to/from work... :-laf

The biggest problem is that the Nano filters are not all they sy they are. After 30k on my stock replacement I can. t clean it enought o that it wount pull down the filter minder, I haven't tried washing it or anything yetbut compressed air i useless on it. now i just use it when i'm cleaning my afe filter

And:

Since the Ea Amsoil filter is cleanable with compressed air, you save $24 everytime you clean it.

SO, what is the physical difference between the Nano filter you had been using, and the Amsoil one you are now using? If they are both cleanable, reusable filters, what makes one better than the other?



I'll be interested in seeing how the Nanofiber 4510 works on my truck over the longer haul, in comparison with the BHAF. Haven't had to clean it yet, and filter minder hasn't moved.

Aren't they talking about the same Nano-type filter that you didn't like earlier?

I don't like oily gauze filters. I've read enough about this one to convince me that it's a pretty good design.

Was just "funnin" on this one and No bashing intended. I'm happy with the PSM kit with the Amsoil nano type drop-in so far. (just being sarcastic about our traffic down here in L. A. and its pretty hard to use high HP as a daily driver when you're limited by driving conditions).

I AM a little concerned as Bob4x4 mentioned about what is "technically" legal and not legal. I would say, choose your mods wisely as it looks like inspections MAY become more stringent in some areas soon.

Yep, we buy what we like partly because this is a hobby to a lot of us and we like our expensive chrome wheels, etc. " It's Clean Fun and keeps us off the streets. " :-laf :-laf

Sorry, I'm still confused - happens a lot more often than it used to... :-laf



The claim you made earlier was:

The biggest problem is that the Nano filters are not all they sy they are. After 30k on my stock replacement I can. t clean it enought o that it wount pull down the filter minder

But that is NOT an "oily gauze filter" - it LOOKS to be the SAME dry-type, cleanable Nano filter as what you are now using? Somehow, the 2 statements don't seem to agree with each other?



What am I missing here?

ABSOLUTELY! :-laf



And as long as we look at, and represent it as such to others, no harm done...

Yea

I didn't make that claim... . MA2LA did

`And as long as we look at, and represent it as such to others, no harm done...

Good point. Have to be careful about being misleading. .

Fact is and has been hashed/rehashed in the threads, different air intake setups don't make a big bang in performance for their buck unless you're up over 450-500 hp minimum and needing more air. Might see "minor" egt & spoolup improvements, but they are very minimal vs what they can cost to install.

As Gary is eluding to, mostly it comes down to cleaning efficiency vs a very small performance increase (Documented!). Frankly, the BHAF style (with your filter of choice) is about the best bang for the buck overall IMO. I just wanted to go to the stock look and see for myself how much real world improvement the cowl hole mod would make. Can hardly hear a difference in the cab, and can't "tell" any loss in performance at all over the BHAF 4510 which was my previous favorite intake mod. The Magnum Force, RE0880, scotty all had their own "compromises" to deal with.

 

[Gary - K7GLD]

Yea

AH - I see - I got your quote in HIS post mixed - my bad!

 

[Gary - K7GLD]

Phil, I post lots of pics here, and am well aware that visual perspectives can get seriously distorted in posted pictures - but your tube from the cowl area LOOKS to have a significant downward slope into the OEM filter box - is there danger of water ingestion in wet weather with that setup, or is it an optical illusion? I still didn't catch what type drop-in element you are using in that OEM box?



Looks neat, gives added air volume capacity, and all external air - good clean mod for tightwads like me! :-laf:-laf

Gary,

I have a hole punched in the bottom of my airbox. Last stock filter change I notice the filter had gotten wet in a spot.

So for all of you doing stock airbox mods just be aware water can shoot up from below I presume from hitting puddles at speed.

Probably a baffle of some sort is all that's needed.

Phil,. . your tube from the cowl area LOOKS to have a significant downward slope into the OEM filter box - is there danger of water ingestion in wet weather with that setup, or is it an optical illusion?

Gary, yes. . It is indeed quite a downward drop to the airbox. I too am slightly concerned about water injestion during a heavy downpour. Just in case I have a cap under the back seat to cover it up. Also am going to look into using a rubber handball (?) or whatever will plug the hole/tube in case of a problem in the field. It will be a test for sure when winter comes again.

I was hoping the 3 small drain holes in the bottom of the airbox would allow water that ran down the tube while its not running to drain out of the bottom.

Also, the bottom of the "Amsoil Drop-In Nano-filter" utilizes a significant layer of foam as the first thing air/water would need to penetrate to get through the filter itself, so that "might" also help. Not sure yet... Could always devise some sort of hood or awning type extension over the intake where it protrudes into the cowl area as one possible improvement to this mod.

Might be a good idea to run a test using the garden hose and simulate a downpour (with the engine off first). Think I'll do that and report back on findings. .

Where does the PowerCore filter element fall in the flow vs filtering vs longevity comparison? Have any independent tests been done that include these elements? I saw the universal elements at

Volant PowerCore™ Filters



What about the difference between dyno runs and highway driving? Have the intake tract temps been measured in a (nearly) controlled test? Seems to me that a truck on the highway COULD benefit from some ram air effect versus a hood open dyno run (hopefully your hood is closed on the road, or you have problems besides air flow to deal with!)
