I fitted my K&N induction kit last Saturday

, through the group buy on the site. What a difference it has made, the sound is fantastic when you go above 3000rmp and the gear changes seem smoother.
I don't know if it has made any difference to the acceleration but i am getting 29mpg and before i was lucky to get 26mpg.
The hardest part fitting the kit was trying to find the best place to put the cold air feeds and finding fixing points for the cable ties. I managed to get both feeds to the right of the radiator behind the lower grill.
If any is unsure (like i was) about buying one, then don't. If you buy it just for the sound alone you will be more than happy

I will have to put some pictures up latter.
