I received an early Christmas blessing this year. I was able to try out a pre-production model of Unique Metal Products' (UMP) long awaited Duramax Super Filter.
A little background on UMP: they've been in the business of making, well, unique metal products out of their Santee CA facility for the last thirty years. Basically if you an imagine it and afford it, they can build it for you. One of their specialties is off road racing equipment. Through their dedication to producing quality off road racing products, the Super Filter line was born. Anyone who has been anywhere near or even seen an off road race on TV knows that they are held in dusty, sandy environments. We all know that we don't want dust or sand in our engines causing damage.
When UMP selected air filters for use with their Super Filter air-box they selected premium Donaldson paper filters. Why do they use paper? The purpose of the super filter is to filter the most particles out of the air rather than flow the most air. Keep in mind however that a larger element and a more efficient air box design will be less restrictive.
In the spring of 2003 UMP first introduced a Super Filter for a diesel pickup, it was designed as a direct replacement on Powerstroke equipped Ford Superduty trucks. Once the Super Filter was released for the Powerstroke, work began on a Super Filter for the Duramax. Around the same time I read a post on an online forum about the UMP SF. I did some looking around online to see what people thought about UMP's products. After looking at posts about their stuff on a few different sites, I decided to give them a call. I got in touch with Cliff Cappos, who is in charge of the Duramax Super Filter project. He gave me some info on were they were at with the project and said to call back in about a month. I called about once a month after that to see how things were coming along. The guys at UMP are very picky and did not want anything to leave there until it was pretty much perfect. That being said, it took a little over six month for them to produce a product worthy of their standards.
The second week of December UMP finished some preproduction models of the Duramax Super Filter. Cliff then sent me one to guinea pig the installation and test it out. Of coarse I got stuck working long hours through the weekend and only got to open it up and look at it at first. My first impressions were wow this thing is big, and wow this is some good craftsmanship. At first I was a little surprised when I saw the wing nuts that hold the filter in and the cover on the end. They look like flimsy plastic. However they are not flimsy, the are very strong, we're talking space shuttle type stuff here. I disassembled it and took pictures so you all could see what all the parts are.
I installed the Super Filter in my truck following the instructions that Cliff emailed me. It was a pretty straight forward install. First remove the stock air-box and air-box mount. Once the air-box is out transfer the MAF/AT sensor and the filter minder from the stock air-box to the UMP Super Filter air-box. Install the Super Filer mount in place of the stock mount. The Super Filter mount is secured using three of the five stock bolts and a provided countersunk hex key bolt. Once the mount is secured in place, the intake tube needs to be attached to the Super Filter. So that it all lines up well it's best to insert the outlet of the Super filter into the intake tube but leave the clamp loose. Place the Super Filter in the mount and adjust it so that the scoop is on the top and facing forward. Once the Super filter is in the proper position, close the clamp, tighten the hose clamps on the intake tube and plug in the MAF/AT sensor. This completes the installation. The instructions from UMP go much more in depth, I just wanted to give an idea what is involved

I put lines between the pics, it came up fine up my computer so I wasn't seeing the problem, I guess Hoot wasn't either. Thanks for the quick fix...

That thing looks military issue.

I have the AFE Stage II on my truck. It seems to me that replacing the corrugated OEM intake tube with something that has a smooth bore, such as the AFE has, would reduce turbulance, thus allowing less resistance in air flow.


I think that is a good looking setup. I'm just wondering how much difference a plumbing change would make in freeing up some extra flow.


What do you guy's think?

Looks pretty impressive, Ox! One question: where am I gonna hang my KD Megafilter under that thing?

what material is the housing aroung the filter is it metal? If it is it will be a heat soak way more than plastic and hot air is no good for performance. Now if they make that puppy in a material that wont soak heat as much as metal get me one now and I know a place that will custom make a silicone duct that has no ribs and bent to the shape and length of the factory intake tube

I guess I left out what it was made of..doh! The air-box is Aluminum and the bracket is steel with a stainless-steel clamp.

Hoot, it looks better than military issue...

Fireman, while replacing the corrugated OEM intake tube with something that has a smooth bore may decrease turbulence, I don't think it would be enough to have much of an effect. I personally like having that corrugated piece in there for it's intended purpose, it allows for movement as the engine moves while running and the fender is not...

Idle Chatter, two steps ahead of ya buddy. I have the mega mounted to the bottom of the SF bracket. I used some stand offs and longer bolts. I'll get some pictures of it up soon...


Clos2sx, I honestly don't think heat soak is a big issue...they use the same type of air box on many different vehicles that race in the desert. I'm interested in the silicone duct idea, smooth bore like Fireman said, yet flexible. The only problem I can think of is that maybe the turbo could take a deep breath and collapse it. How rigid is it? Maybe a big spring inside would prevent collapse like the old radiator hoses.

Thanks for all the good replies guys. I'm glad to be able to present this to you all. I should be able to buy one of the first production models when they have them ready. Hopefully can hang on to this one till then and make some comparisons. I'll let you guys know as soon as they tell me that they're ready to sell them.

Ox, Nice pics and filter. How do you keep the engine bay so clean? Mine has never looked like this, probably never will.

Nice, real nice!
Almost to nice to swiss cheese, almost. Who's going to do it first! You know you have to, can't stand it, gotta do it! Drill, Drill!
Just kidding, but there does seem to be a nice area beside the slot for a few holes.

It's not just the engine bay - I've seen the BlueOx truck first-hand at Grand Rapids and the man keeps a "clean machine" inside and out!



Looking forward to the adjusted Mega mounting info, Ox.

That air filter set up is great!! I've got to pick me one of those up when they hit the market! We sucked up a filter in a 99 P-stroke. Engine went out around 70k in it, do to sucking up to much crap from checking pivots and dirt roads. We were always fighting air filters with that pos. I don't think any of the OEM pick-up filters are very good for real world (Farm) use. We may have to get one of those filters here in Africa for our rescue truck.

Very nice set-up. I could see me buying one of them once they're available.


Thanks
