Replacement air filter and warranty problem

[DEllerbe]

Has anyone considered fabricating their own filter box with two stock size filters? Effectively doubling the surface area, decreasing pressure drop, increasing volume of air to turbo and doubling time between filter changes sounds like the IDEAL settup. Or maybe even mount one of those heavy equipment cylindrical filter elements in a custom filter housing??

Has anyone put a BHAF in a 2003 or newer?

An interesting idea...

Sounds like an invention in the making. Is there room for all this?

Being doing a little research on filter systems as I am in the market for one. There's alot of feed back on K&N and AFE but not much on "Airaid".



Any you folks out there got any experince's or comments on Airaid filters? Pete

No need to re-invent the wheel - if the goal is more square inches of filtering surface, the BHAF and several similar arrangements already do that - at a price in underhood space - attempting to do the same with 2 flat filters would likely create the same mounting issues, with no advantage in filtering ability or cost savings...

Here is Amsoil FIlter Chart:

Amsoil filters

Re lawdog's post, I don't doubt that Amsoil filters are good products. But replicability is a criteria in any comparison and, perhaps with good reason, I never see Amsoil filters tested side-by-side by other after-market manufacturers.



I also note that Amsoil didn't test aFe filters in their oil-wetted comparison. Perhaps with good reason here too?

What the heck does lawdog's graph show? Define "excellent" and "poor" objectively.

It's a typical Amsoil graph the company uses when it wants to avoid a discussion on micron filtration. The theory is that particles of dust and contaminates can "penetrate" OEM paper filters but get hung up in multiple layers of the oil-wetted Amsoil filter. The air, of course, is allowed to flow through almost unobstructed - that is, unless the user has applied too much oil, in which case it won't work any better than other filters - and may even work worse because dirt-laden oil and silicon can be drawn into the turbine. That's what makes the K & N filter verboten for use in a Cummins automotive application.

I've been asking this question for months with no good reply. I don't think the newer 3rd gen owners know what the heck a BHAF is and most aren't into bombing or experimenting. But some of the folks are moving over from the 1st and 2nd gen trucks and know all about bombing mods. I'm sure someone will soon come up with a good and reasonable BHAF.

Possible Problems

Blakers:



There might be problem using BHAF on 3d gen with the air filter in the front of the truck getting wet. You would need an enclosure to protect it or end up positioning it wher it draws hot engine air.



could be you're not getting any hits on this 'cuz no one is doing it.

As a writer, I might suggest that folks who use acronymns (BHAF, BOMB, etc. ) add a parenthesis in your narrative and spell out what you meant by the acronym so newbies will not feel intimidated.



I'm not criticizing anybody, but sometimes we oldies toss around terms that only other oldies know and it's frustrating for a newbie when it takes him 6 months to figger out what the hell we're talking about.

Stick to the factory filter if your going to keep it for a long time. The other filters let in more dirt. ie microns. after many miles that begins to creat what we call ring wash out. It might be a pain but I believe in preventive maint. The gain is very little and not worth it. I have also seen check engine lights becasue of this. When they saturate the filter too much during cleaning it goes trough the intake and clogged the map sensor. I have not personaly seen dodge revoke warranty because of the choice of air filter. When I talked to the factory rep. they replaced the engine and then go after the air filter company. That was 3yrs ago. I can call them and ask if your interested.

Daimler/Chrysler dealers used to sell K&N replacement filters and cold air systems through their performance division-Mopar performance. I have seen many K&N cold air tubes crack. In the beginning they were getting replaced under warranty,then it seemed as the number of failures increased,the systems became unavailable through the parts system. Now if you check this years Mopar performance catalog you will see many AFE units offered through Mopar performance.

The nice thing about the BHAFs is they are factory filters, but made for semis, farm tractors, or some other large piece of equipment. They filter air just as good as the dodge filter, but allow much more air flow. Many of them are used on the same Cummins engines in an industrial application.

My thoughts exactly!

I'm pretty well convinced that I will be switching to a BHAF Fleetguard marine style filter after my next oil change and analysis - I've been waiting until I had enough break-in miles on the truck for readings to stabilize, and will have about 27,000 miles on the engine next change - it will be interesting to see the difference between my K&N with the drilled air box, and the BHAF... Unfortunately, it will be close to a year the way I drive before the BHAF analysis will be done...

 

[dezeldog]

I used a BHAF on my previous truck 98. 5 auto and my last analysis came back SI-3 that was with 292920 mi on the clock. I' d like to see if I can get one in my 03. I don't care much for the "oilers" jmo.
