On this car, I do not believe much improvement can be found.
I still have the Carbon Fiber RM (I believe) intake with open ended K&N cone filter the PO installed on my car. (not open ended, but filtered end, close to the side intake opening)
Have the stock air box & new OEM filter I will install (thought I would have done it a couple yrs ago) but have not got around to it. This set up does sound really good compared to stock, but doubt if it adds much if any HP.
The sound alone may be reason enough for many? It is pretty cool 4k and above..........
There has been tons of debate here over K&N cone as well as flat filters having negative effects on our cars. But I am not too concerned.
If it were me, I would look to spend the $$$ elsewhere.
Here is a shot prior to my ownership.
