I have tried to look through the history to see if this has been asked before but didn't spot it.
Has anyone got any experience with cold air induction kits. There seems to be a huge difference in cost on the internet with a K&N system for £220+ against an unbranded system for £45.
Questions are:-
1. Is it worth adding a kit
2. Do they deliver any real (perceivable) gains
3. Can anyone recommend a system.
Thanks
