The Autodelta filter I got with my Carbon Fibre Air Intake does not seem to be a K&N filter, it's thin, red foam (looks like foam?) with the Autodelta logo on it. It's a LOT thinner than the big fat ugly paper filter the car came with. When I first took it for a drive I was shocked at the difference. The car felt like it had a lot more power, although this feeling must just be better throttle response.
The 147 "feels" slow. You put your foot down and it feels like it has to "think" a little before it really takes off. But since installing the Carbon Air Intake and sports air filter... as soon as I put the foot down, even a little, the car just goes.... SUPER smooth, responsive and generally feels like I am doing 0-100km/hr in 5 seconds
VERY happy chappy I am.
If you could only see just how ridiculous the old plastic carbon air intake is. I look at it nearly every day as it's up on the garage wall, to remind me of how crap some "default" parts are on the 147! It's a big, plastic tube with 3 chambers on it, all of which lead to no where, it's like pushing air into these chambers and blocking it in there. All slowing you down!
There's also this filter you can get for the 147, it looks more like a K&N. It looks good to me:
NOW: Can someone tell me, is the Autodelta filter foam? Is it better, or is the K&N (or green japanese one above) cotton filter better? Would they feel any different to each other?
