Just wondering whether or not there is an advantage to replacing the stock air snorkel with a Ralliart style,
Also thinking of maybe replacing the air filter with a K&N one
Any thoughts or suggestions would help
thanks
(Also, I have a 2012 VRX)

Yes
Not an oil soaked airfilter

Try eBay, GumTree and wreckers for them.

Also there is plenty of info on this topic already posted, do a search for it.

And welcome to the forum.

Huge advantage to dropping in a RA snorkel.
Drop in a K&N air cleaner. Wrap the intake
Get an ECU tune
Go nuts drop on extractors
You will be very pleasantly rewarded for your time and $
