Best Filter/Air Intake?

[Duluth Diesel]

I've already ordered everything and will be doing the install this coming week on my intake setup. The setup is called The Whistler Intake.

The link you posted shows him using a 6080 filter. The 6081 is bigger. I was just down at AMSOIL Corporate HQ in Superior, WI yesterday shooting photos of them all. Get the 6081 if you go the 6" route. Also consider this: Your turbo only sucks through a 4" hole anyway, so you aren't gaining a whole lot with a 6" flange. Also, the entire 60 series filter line are quite a bit smaller in filter surface area than the 4091 and 4510 filters. For big air and matching intake diameter size, and increased dirt holding ability, I feel the 4510 is a better match. I shot some photos and did a writeup here: http://www.cumminsforum.com/forum/a...15611-nanofiber-air-comparative-pictures.html



This will at least give you an idea of how these filters look compared to one another. The AMSOIL website doesn't show pics of the individual filters, so I went and did it myself. Hope this helps.

Chuck,



You speak too logical for me What you say makes sense as far as the larger filter surface area of the 4510. I think the larger intake opening (6 inch -vs- 4 inch) right up front is what makes the whistle from the turbo louder. I believe with either the 4510 or the 6081 you will get a better breathing intake, but I like turbo whistle so I'm gonna go with the 6081 Oo.



By the way, the Amsoil Ea filtration family is top notch. Amsoil added a notch in their bed post with the Ea lineup (oil and air filters)!

I personally have never compared turbo noise between a 4. 5" Nano and a 6". I will say this though, when I went from my stock airbox on my 2002 to a paper Fleetguard AH19037 BHAF, I thought the turbo noise was crazy. Then, I went to the Nano filters, and it just about doubled the turbo noise again. It could be louder with the 6", I don't know, but I do know that if you want your turbo to sound like an F-16, get a Nanofiber.



I agree, the Nanofiber technology from Donaldson, brought to use with AMSOIL, is a leap forward in filter technology that has been long overdue.

I am a fulltime RVer and could care less about turbo whistle. In fact, with me, the less the better. I just purchased an 07 CTD. What is a good filter that doesn't increase the turbo whistle?

 

[Duluth Diesel]

To get the best filter but keep turbo noise down, the Nanofiber drop-in for your factory airbox is the best bet. You'll get increased airflow, better dirt holding ability, a resuable filter, and still have the stock air box to keep it quiet. The cone filters are the ones that really whistle. Keeping your stock airbox and just upgrading the filter inside it would be the best bet.

AFE for safe filtration and lower EGT.

 

[Trizae]

other than heat absorbation/disapation,,, is there any advantage to replacing the afe intake tube with the cool blue

AFE for safe filtration and lower EGT.

Safe? Define safe. Because the oil/dirt gets sucked out of an oiled filter, effectively "dusting" your engine? Oiled filters are starting to be phased out for turbo charged engines. The filter media is unable to hold onto the oil under the high air demands of out turbo diesels. On naturally aspirated engines, oiled filters seem to work. The oiled filters are designed to suspend the oil in a cotton/gauze or foam matrix, and the oil catches the contaminants, and the filter media holds onto the oil. It is essential to oil these filters so they can filter air. With the CFM demands of a turbo diesel, the filter media has been shown to be unable to hold on to all the oil. The oil and dirt it has captured are released up the intake tube. Nanofiber air filters use a proven filtration technology created by Donaldson and built into a universal filter and OEM replacement filters by AMSOIL for our trucks. No oil, no wet washing. Better dirt holding ability, and better flow. I have photos of that an oiled K&N cone filter do on a turbo charged engine. The oil, when applied to a K&N filter, is red. What is being wiped out of the intake tube is black. That means dirt in oil, on the wrong side of the filter. I'll never put an oiled filter on my engine.

I've used an oiled filter in the past, but have since gotten smarter. Only dry media for me.

Chuck - "metal_miner" here from cumminsforum...



I finally installed the Ea 4510 filter this weekend to replace the AFE PG7 filter I had. The twins were sucking oil and crap out of the AFE like crazy. Portions of the intake pipe from the AFE to the primary turbo inlet had some quantity of black, viscous oil residue on it.



Normally, I don't buy into the Amsoil advertising, but the fact that Donaldson was heavily involved in this filter made me look closely at this filter. The 4510 gained more filter area by making the intake flange shorter than the AFE as well as going with the oval shape.



BTW, the filter barely fit under the hood in the BD airbox after some creative hammering. The oval shape of it really makes for a good fit in weird spaces. The turbo whistle wasn't that much louder, if louder at all, than when I had the AFE installed. I'll post pictures soon...

Jstieger, pics would be great to see! Post 'em up!

Intake

I have the S&B. Intake tube has been clean so far. Works good and looks nice too. It was the cheapest setup I found and outstanding claims of filtration.

AFE oiled filter meets DC standards for filtration. As far as I know AFE is the only oiled filter that does this. I have a K&N filter on my Jeep Wrangler but would never put one on my Ram.

 

[Duluth Diesel]

AFE oiled filter meets DC standards for filtration.

Show me written proof of that.



Please and thank you.

 

[JVantreese]

Show me written proof of that.



Please and thank you.

OK, because you ask so nicely I will provide you with more then just my opinion. Check out www.genosgarage.com/prodinfo.asp?number=afe-75-10811. Regarding the AFE Proguard 7 they state, "this new filter media meets 99. 5 cumulative efficiency that is the manufacturers's minimum requirements for filtration. "



I have no dog in this fight as I do not get a commission on the sale of AFE products. I am just passing along info that I feel comes from a reliable source. If you are happier with a dry filter then by all means please use one.

Genos is good stuff. The info is much appreciated! I do prefer an oil-free filter, but thank you for kindly passing that info along to me.

I sent a question asking about ordering one from 4wheel parts and they said they were special order. But no prices were mentioned.

#4510 installed pictures

I assumed a uniform cone angle and measured the middle circumference of each filter. Area = height x length. Length = circumference if the filter was "rolled open", so...



AFE height = 8" x 23. 375" average circumference = 187 sq. inches



AMSOIL height = 10" x 23" average circumference = 230 sq. inches



Assuming that the pleat depth is the same between the 2 filters, we get +23% increase in area with the 4510. The 4510 had to be adapted from the 4. 5" inlet to my 4" BD primary intake pipe and with creative hammering on the filter box, the filter barely clears the hood.
