Air filter

[RayB]

Has anyone made a filter that fits in the oem box, like the k&n did on the older trucks

 

[ScottBrown]

Yes AFE makes one that drops in the original box. it is similar to the K&N . You can clean it and offers greater air flow.

Amsoil has one, TS 189. I did a little checking on the filter minder and it only takes . 5 inch of vacuum to set it at 100%. So keep that in mind when you are searching for an air filter. TBOB

only takes . 5 inch of vacuum to set it at 100%.

is that in inches of mercury?. . if so, that is 1. 5"h2o... too low. i think up to 20"h2o is ok at full boost... stewart warner makes a filter restriction in cab 2 1/16" gauge that reads 5" - 40" h2o... i don't think it has a tell-tail on it though, it'd be nice to have one of them on it.

aFe has a drop in replacement filter 30-10102 and a complete replacement air box and elbow with conical filter 50-10411 in the Magnum Force line.

Is this TS189 something new they have come out with. I don't see it listed,they show nothing for the 03. TS106 is up to 02.

lschultz,

Yes the TS-189 is a new Airfilter for the 2003 CTD. It does fit the box.

I've been running an Amsoil prototype air filter in mine for about 10K mi. now, and it works great. Instead of pulling the filter minder down to 65%, it only pulls it down to 35%. I'll have to cut some holes in the bottom of the box.

I can't find a listing or anyone who has Amsoil ts-189 for the 03 cummins. Can anyone help?

 

[amsoilman]

You can now order an Amsoil 2-stage reuseable oiled-foam air filter from Amsoil Inc. It is a TS-189 for the 2003 CTD.

Thanks

I just order one.

What is the highest flowing airfilter I can get for the stock box. What I'm thinking about doing is purchasing the above mentioned filter, and modifying the bottom of the box drastically to allow more cool air to enter. That way everything looks stock under the hood



Will this give me the sound like an open element?



BTW, 5" exhaust is on the way

To answer the question regarding airflow, one must look at other things as well when it comes to airflow.



First off there is the size of particle the filter needs to filter out. In general, 5 to 25 micron particles are of the greatest concern when it comes to air filtration, as these size particles can and do get into the smaller clearances of bearings and such other mechanisms like valve rocker arms. If the filter is to restricted to filter out smaller particles, then the airflow is reduced. However, if it is too open then the filter is not efficient, and will allow larger particles to go through the media. Air filters are generally least effective when new, and will improve efficiency as the filter media becomes loaded. However, as this occurs airflow will decrease.



Airflow is indicated and measured in (CFM) Cubic Feet per Minute, and one must know the amount of restriction at the noted airflow in order to compare filters. At an airflow rate of . 25" water (H2O) utilizing a manometer, the Amsoil oiled foam filter had 200 (CFM) Cubic Feet per Minute compared to a Fram paper filter 80 (CFM) Cubic Feet per Minute. The K&N when oiled as per the instructions for off road service measured 100 (CFM) Cubic Feet per Minute. All these filters were of equal size.



Flow Restriction is measured as the pressure differential between the inside and outside of the filter element, and is expressed in inches of H2O or mercury. This is usually tested using a manometer with one side of the unit connected to the "inflow" side of the filter (higher pressure), and the other side of the unit connected to the "outflow" side (lower pressure). The pressure difference between the "inflow" side and the "outflow" side is then measured on the manometer. Our trucks have a similar device already on the air box that measures the pressure differential, called the "filter minder". As the air cleaner media becomes clogged and the air pressure drops on the "outflow" side of the element, the yellow disc will travel down and indicate when it is time to change the air filter element.



Life expectancy and efficiency of air filters are tested using SAE test method J726C where they introduce a measured amount of "AC Test Dust" of different particle sizes in the testing apparatus. The results of the tests are measured in "percent" of contaminant removed over a given amount of time.

Where can I get the amsoil filter and how much $$. Does it have a million mile warranty like the K&N? Does it come with a service kit including the wash spray and fresh oil? If not, where do I get the service kit? Can I use the K&N service kit?

 

[amsoilman]

The retail price is $47. 50 + freight 2. 0 lbs. THe filter comes already pre-oiled, and is generaly good for 20-25,000 miles of normal driving. There is no special "kit" to clean. It is cleaned with a high detergent dish soap, rinsed with water, dried then re-oiled using a "tack oil". This oil is also available from Amsoil. One 8 oz. bottle will do the filter about 3 times. The filter does have a "Lifetime" warranty.



Hope this helps.
