Hi My names Adam & I have just traded my Suzuki Cappuccino in for a 2004 red Copen with black leather interior. I'm looking forward to start using it as my daily driver. Tuning items seem to be harder to get then for the Cappuccino. Can anyone point me in the right direction here in the UK? Can I buy a replacement sports air filter to fit into the standard air box. K&N don't seem to do one.
