Focus RS
Pro Alloy charge cooler well made and good performer.
Air filter wise I would stick with std unless you find dyno graphs to prove any substantial gains.
Dream science prob better than bf for several reasons.
Decent resale value
Multiple maps
Cheaper to reset
Forge recuic valve

I have recently taken my K&N GenII off of the car and then put it back on the car as I missed the noise 
Gains about 4 bhp extra but loses a bit of torque I think. Either way I am not fussed about performance.
With the K&N GenII you will hear the recirc dump valve a lot clearer and it does turn heads. Never had a problem with idling etc.
