It sounds lovely & is VERY easy to fit. Here are the 3 quick and easy steps:
1) Buy the K&N.
2) Take one st_owner100 & hand the K&N to him.
3) Stand and watch as he fits it.

Seriously it is very easy to fit. It shouldnt take you more than about 10-20 minutes. You are left over with a lot of "extra" bits. You can put the big plasticy box bit with Duratec ST on it but I havent. Mainly because its not really needed and also because I cant get a plastic pipe off it to put it back on

The K&N should come with a fitting guide but if not there is one here:
