Currently running the Mountune RS500 FRS CAIS and my K&N has seen better days, on mountune's website it suggests going for the faster flowing V2 cone but also heard good things re Green Cotton Filters, anyone using one on their RS and if any good recal the part number ? ,

Thanks

 

I thought there was a process to clean the K & N and off you go again? Nice car BTW.

 

thanks mate, you can but theres drying time and all that palava, plus I know I have the older style filter so fancy either going the faster flowing v2 or green route as a small upgrade

 

Gotcha...

 

Bought the Green one in the end as better flow and far more positive reviews over either of the V1/V2 K&Ns
