I have the diet engine 1.2 8v and fitted a fiat chinquicento (who knows the speeling lol!!!) K&N to mine, and the results are....
1. I use alot of petrol
2. I have a huuuuuuuuge space at the back of my engine now
3. I have one cold air feed
4. I notice no added performance whatsoever
5. It sounds the dogs bollox
So make up your mind from that? Im actually thinking of taking it off and replacing it with the std one, as i does do your head in after a while, lol!!!
I dont have an exhaust either, god im getting old!!!
