If i were to add a S&B cold air intake on my 2011 diesel, without any type of programmer, would it mess with the trucks on-board cpu, or void the trucks warranty in any way?

 

Read this information and watch the video and decide for yourself.

I had an oiled S&B on my '03 for awhile. It returned great fuel mileage and low-end throttle response....when it was clean. A few weeks of driving later, not so much. Worse, I found dust in the intake tube the first time I took it apart to clean it. This was an early design though, maybe things have gotten better since then. Anyway, that combined with getting sick of cleaning it and having to wait overnight for it to dry, I went back to stock.

Just my $.02, save your money for something else. Besides, the deep filters on the 4th gen trucks should allow for plenty of airflow I would think. Really no advantage to an aftermarket air filter (and based on the previous post- some definite disadvantages).

 

Sounds like great advice from both...
Thanks!!!

 

LB164,

to answer your questions, absolutely not. However, if you had a dust out condition, that could be caused by other problems as well.

I have done two oil analysis' since I installed my S&B. Both indicate contaminate metals were well within tolerances for Silicon, which typically comes from dust and dirt (but not always), and most commonly enters through the air intake. This indicates my S&B is performing just fine, in other words, doing what a filter should be doing. My last oil sample showed Silicon was down by 1ppm since the first sample. I was going to take another oil sample next week until I realized it hasn't even been 3K miles since my last sample, so I will wait another month or two. There is a thread in the General Diesel Discussion forum titled "The Oil Thread". I've been posting my results in there and will post my next one in there when it is done - if you are curious about the results.

Now then, about the warranty, if you were to have a dust out condition, there are steps a dealer has to take to verify the cause before denying warranty. They can not automatically assume the dust out was caused by the use of an aftermarket air filtration system - check out this link - Dust-Out Diagnosis For Cummins Diesel Engines for the procedures the dealer has to take when they suspect a dust out condition. They also have to prove X component (especially if it is aftermarket) caused Y failure before denying warranty (federal law).

On to aftermarket filters/systems. My recommendation is to stay away from any and all oiled filters, whether they are for CAI or replacements for the stock filter. There are better filters out there than oiled filters, some are cleanable with only low pressure air (AMSOIL) and some you toss after x miles/months. My S&B has the oiled filter and I don't like it. I wish AMSOIL would come out with a bigger filter to replace it. If you choose to get an S&B, get their dry filter instead - same goes for other aftermarket CAI's - when you install it, take care in keeping the entire intake system clean when removing the factory intake and preparing to install the aftermarket.

Please note, manufacturers will almost always make recommendations specific to how they tested their products and encourage using one of their products ($$$) and in a way make it appear using anything else is a bad thing. They don't have the time to test every single filter, but use one that meets their intent and makes their recommendations based off of that.

Here is another food for thought - I think I got better mileage with the factory intake than I did with the S&B and have been thinking about going back and replacing the stock panel filter with an AMSOIL replacement to test my suspicions.

I know this is quite long, but I wanted to give you as much information as possible to make an informed decision.
