Hi:



I was wondering if anyone has installed an aftermarket CAI on their truck. It looks like S&B is the only company that has one out. Any others that you would recommend instead? The test results show a 59. 4% better airflow over the entire CFM spectrum.



http://www.sbfilters.com/product_display.php?id=2898



Their specs for the CAI kit is:



Airflow Rating: Improvement in Airflow vs Stock Induction System:



Flows 78. 9% Better @ 311 cfm, 54. 8% Better @ 620 cfm



Efficiency Rating: 99. 16% Efficient - ISO Course Dust
The Dodge filter is 99. 83% efficient for traping dirt.



The test results can be found at: http://www.sbfilters.com/pdf/iso_5011_2898_Test%20Report%2075-5015%20Rev020807.pdf



Thanks in advance,

Brad
 
I haven't seen any others either. Let me know if you put one on and how it works. Are they claiming any increase in HP/Torq? I am going to call Banks tomorrow and will post what they say.
 
Air filters and cold air systems have been discussed occasionally in the TDR magazine. One very important point stressed is the ability to deliver CLEAN air, not just air flow. For instance, if air flow is the only issue, just don't run a filter. It will wreck havoc and destroy the engine, but that sucker will FLOW.



Many folks have silica analysis performed to determine the effectiveness of filtration. Silica is a good indication of filtration performance. One side by side comparison of flow and filtration revealed data that said some of the high flow filters/intakes were not very good at filtration. Actually the stock filter was rated very well, especially compared to what an author described as the "filter on a stick" aftermarket systems. Isolating the intake from the hot air under the hood is another issue to consider.



A practical and effective system for good filtration, cold air, and improved flow for the 5. 9 is to increase the stock air box inlet area, ducting cold air into the bottom of the box. I can't see why that approach would not improve the 6. 7 system.



Another comparison of dyno results showed little HP/Tq improvements with aftermarket intake systems. I see the aftermarket products as very expensive eye candy and not particularly horsepower/torque adders. The life and health of the CTD is at stake if filtration is compromised.



This is what I have been using and I'm very happy with it: https://www.turbodieselregister.com/forums/showpost.php?p=1431823&postcount=2
 
I spoke to Banks this morning and they just got there 1 ton dually 6. 7 dodge about a week ago. They said they like to put some miles on it before they put it on the dyno and start working on improvements. It sounds like it will be a little bit for aftermarket Banks products.

Hi Les:



I agree with the concern of the filtration which is why I included the test results in my question. The stock filter is 99. 83% effective and the S&B is 99. 16%.



They are not claiming increased HP/Tq, just airflow. The only other difference besides this minor filtration effectiveness is that the stock filter has a lot more capacity. I assume that meant capacity to hold dirt before it it needed to be cleaned compared to the S&B.



The one thing I do like about the S&B unit is that it comes with a precise measuring tool for applying the oil. I used to have a K&N filter and that was a big concern of over oiling it.



The unit is sealed in the engine compartment and it appears to pull the air from outside (thus the cold air intake).
 
Sounds like you are doing your homework, Brad. Try a few out and tell us what you like. I'll be moving to a 6. 7/auto not too long from now and appreciate all the "trailblazers". Thanks!
