The standard intakes on Alfa's are not bad at all.
which is the exact setup ive gone for and yes it hasn't made a blind bit of difference but does sound a little nicer.
you can do these kits all you like and fall for the marketing all you like, the truth is they do very little. the inlet manifold is the same and the throttle body is the same what can a fancy £150 air filter do?
save your money and put it toward a re-map.
