Thanks, TDR Staff

New engine

Its time for bigger turbo & injectors on '06

Outterwears can make you a cover for any filter you want, just send the dimentions and they make the cover. I would think with this filter you would need a cover with the cone shape built into it so as not to restrict the flow.

Thats cool, I am sure NOSPIN4ME would want a red one. In order for this filter to sell well someone is going to have to offer up CFM specs for comparisons.

I am guessing there is a special cleaner needed for service??



It looks like the dimensions are more easy to fit than a BHAF. I tried one of those and IMO was too big stuffed in a 3rd Gen. I know others have done it but the lack of clearance makes a clean mounting difficult.
 
It's in!

We put one of the two filters that Chuck brought down into my truck. First impressions are:

1. It's cute... :-laf Looks kind of small since I am used to the BHAF

2. It's a little louder on spool up.

3. I think EGT's are lower. It seemed like the EGT needle wasn't swinging as fast when I romped on it.



I have a brand new BHAF still in the box, so if I have time tomorrow I will try to do some back to back runs for comparison. Nothing fancy, just seeing what the EGT's do.



Truck mods are: DD2's, APB, old-school VA, 38-psi boost, and a CC (crappy carter) pusher pump.

Thanks, Billy. Looking forward to your analysis.

I'll second this. Like Hohn was originally trying to do, we want something significantly better than the BHAF. ;)
 
I took both filters out on the interstate and some back roads, making a loop. After the first loop with the new Wix BHAF, I put the Amsoil filter in and repeated the same loop. The truck was unloaded.

At 78mph, my EGT's were 700-degrees at 12-psi of boost on both filters (head-wind).

At 60mph on the back roads, my EGT's were 600-degrees at 2-psi of boost with both filters.

The third test was rolling at 55mph, and then punching it at the base of a hill until EGT's reached 1200-degrees. The BHAF reached 72mph, and the Amsoil reached 73mph. I would say the perform pretty much the same. Of course, YRMV.



I would like to see what it does on a more heavily modified truck, where the BHAF has been known to suck in.

Honestly, with my mods, I really don't need something that flows more than a BHAF. However, the fact that the Amsoil isn't a throw-away is important to me, and is a significant advantage to me.

I believe Chuck was going to do some digging at Amsoil to get the numbers. Also, the only special cleaner you need is a vacuum or compressed air at 20-psi.

That is tiny in comparison. But if it flows the same and is reusable/cleanable, then it should be a worth while investment.



I've got one ordered, should be here sometime this week. I'll be on the dyno May 20 where I'll compare numbers with the Amsoil and the Fleetguard Marine BHAF that I'm currently running.
 
I also recived one of these filters from Chuck and i like it very much, first thought was like Will said its tiny. i got one of the first ones and let Will try mine and he liked it so he bought one from Chuck. THANKS CHUCK!

I think it would be a plus to have an 8" diameter filter even if its not needed.

The 6" might give the mighty CTD a complex when the hood is open.
 
I am working on CFM specs. I'll keep ya posted.

No special cleaner necessary, and no oil. Just an air hose using 15 to 20 psi of air to blow it out. That's it. Simple and dry.



It will fit a 3rd gen, but I know some of the newer trucks have a mass airflow sensor that will have to be retained somehow that mounts to the factory airbox. If you 3rd gen guys can get around that, then this filter will work great.

We ran it on BillyDiesel's truck and TurboTweaker's truck. They bought the two filters I brought down to the meet and are running them right now. So far BillyDiesel says that his EGT's are not coming up as fast as they did with his BHAF, and Tweaker says he can't get the 12 valve about 1100 EGT, but that may just require more fuel to fix. He removed his fuel plate at the meet, so we'll have to see how it works now.



We don't have CFM flow measurements yet (I'm working on it) but we do know that the Donaldson media flows more CFM per square inch of filter media that pretty much everything out there (that still filters worth a dang). Some people have asked for a physically larger filter, but size doesn't equal performance. If that were the case, 7. 3 PSDs would spank our little 5. 9s. Since the filter media flows more CFM per square inch compared to paper/cellulose, it is worth at least considering that this filter, although small, could match or beat the CFM from a BHAF. From what we are seeing based on EGTs and seat of the pants, this may indeed be the case. Look at a BHAF. That filter media is 2. 5 inches thick. 1 square inch of that 2. 5 inch thick media doesn't flow as well as the Donaldson Endurance media, which is about 0. 125 inches thick. Believe it. 1 square inch of the Donaldson media flows more CFM, so a physically huge filter isn't necessary. The BHAF is that big because it has to be to overcome the poor flow characteristics of 2. 5 inches of paper.



Here are pictures of it installed on my truck.

:-laf:-laf... yep, i think so too. that filter may flow good, but it looks way too small under the hood. . just like having those aftermarket intake manifolds [highram... ] looks good under the hood. .



in this case, i don't think smaller is better.
 
The turbo noise was louder with this new filter compared to the BHAF. Sounds like the turbo is going to come through the firewall and eat you. :D

I sold the Amsoil filter off my truck, so I'm currently back to me old BHAF until I can get back over to Amsoil and grab another one.

UMMmmmm - excuse me, but *I* musta got short-changed on my NAPA BHAF - it has the same relatively thin paper element media as all other paper air filters I have seen - or am I missing something here?
 
Take your BHAF off, and pinch the thickness of the total filter media, from the outside of the filter to the inside. It is about 2 or 2. 5 inches. That is a lot of paper fluff to pass through. I am basing this on my Fleetguard AH19037.
 
OK, this is what I've been given from Amsoil TechService in regards to flow of these filters. I guess I'll just give you guys the data and we'll try to desipher it best we can here. This is what I've condensed from my discussions with Amsoil. I think we'll have to find someone to do testing for us head-to-head with a conventional BHAF. -Chuck



"The main advantage AMSOIL is promoting with the new Ea air filters is that they are more efficient, with some advantages in air flow over cellulose filters and, in fact, over TS as well. If we went head to head with K&N the Ea air filter would most likely not flow quite as well, but better than cellulose filters. To better serve our dealers and customers, AMSOIL partnered with worldwide leaders in filtration to develop the EaA nanofiber filter (read: Donaldson). The EaA filter offers higher efficiency and better airflow than foam, oil wetted gauze, and conventional cellulose filters. The EaA filters offer less restriction than the foam filters, at 200 scfm the restriction is 0. 8 inches of water, while the foam filter is 1. 1 inches of water, the oil wetted gauze filter is 0. 6 inches of water at the same volume of air flow. Using SAE J726 (ISO5011) test protocol and employing a mixture of A2 Fine Test Dust and carbon black to simulate on highway driving conditions, and cumulative efficiency is 99. 5%. Oil wetted gauze filters, when tested with course test dust, have an efficiency of 99. 1% while the foam filter was 99. 5%. This testing was conducted at Southwest Research Institute. The average pressure differential fro the EaAU filters (read: the whole product line average) was 4. 7 inches of water at 450 scfm. The Fleetguard AH19037 (read: BHAF) was not tested. The Ea air filter line will withstand water per normal operating conditions but are not meant to be submerged or washed. Due to the fact the AMSOIL EaAU filter is high efficiency (removes more dirt), it will have a larger pressure differential than wetted gauze versions.
