I have a 2011 RTL and I’d like to install a K&N CAI. I am fully aware the ridgeline already comes with one and the mod is unnecessary, but I still want to try it mainly for intake noise and mpg. I also understand that there isn’t an available upgrade for the 2009-present due to the mass airflow sensor. Is there any adapter available that would make this mod possible? Or would the drop-in filter that is compatible offer any mpg or sound gain? I apologize if this has already been asked.
