Marked improvement in mpg (although only 2-3mpg) no difference in sound, possibly slightly better pick up in 1st. Would buy again if needed and would recommend for other legacy owners. As an aside my OEM filter wasn't that mucky when replaced.

This product was recommended on the UK legacy forum so thought I would give it a try. Crisper throttle responce noticed and less tendency for the car to change down when under load. No nasty inlet roar so that's good by me. I've also got rid of the inlet resonator by the way. Still monitoring fuel consumption, initial figures suggest it may have improved or be about the same My car is the 2.0i sports tourer 'BP5' and the filter fits spot on.
