get a cai off ebay £30 and chop it down ,like i done .You have to get a new filter. I got a new second hand one for £25 off ebay. God i love the sound it used to make and better power then having it in the wheel arch.

You can run a cai with your k&n on the end, but watch deep pudles and it lags a bit , i swear the uprated panel filter felt better.

Might invest in a new filter then mate and do what you done. why is it better to have it where you got it and not in the wheel arch? Would it not get more cold air from wheel arch? Or it not work like that?
