Whats the code for the screw on type i was in halfords and the champion ones are f306 but M&P in swansea have KnN kn303 one or hiflow hf303 with 4 ltrs of oil for £26

Just buy one for an fzr600r or thundercat

I use the K&N KN303 filter. No need for a special tool to remove them in the future - just a 17mm socket.
