Has anyone installed a Banks or K&N cold air intake system on this 6.7 and did you notice any improvement in performance or mileage?

 

Banks and K&N are great marketing companies

I have an aFe CAI on my truck, but there are others that are just as great. You will hear a lot of opinions on them. Here's mine:
1. They look cool.
2. They can and will pack with snow in snowy environments.
3. There is no difference in performance on a stock truck.
4. You do not need to be tuned to run them (can be run on a stock truck).
5. You will hear a slight turbo whistle with them that sounds really good and leaves you wanting more.
6. The rest of the sound change is wishful thinking
7. There is no increase in power or mileage.
8. Did I mention they look cool?

 

For me, hearing more of the turbo....worth it just trying to pick one now

 

S&B Cold Air Intake System (Cleanable Filter)

Probably your best bang for your buck right here...

 

sweet, thanks...been looking for an answer that simple

 

Savage nailed it!
Ran an aFe on my D-Max, looked cool, turbo whistle.
I will say it was a "lifetime filter", super easy to clean & maintain. Used the same cleaner process for the atv's & dirt bikes, K&N cleaner & filter oil.

 

I ran a banks on my 6.4. Excellent fit, tight connections and kept the intake nice and clean. Ran it for most of the 5 years I owned the truck. Never a problem with snow or rain.
