Cost no object? BMW Performance Intake (Euro model available?). Otherwise, the Euro intake. The stock unit is good, runs cold air, has an excellent filter (K&N, AFE slightly less restrictive, slightly less filtering), but is a PITA for filter replacement. Most of the other intakes make more noise and shave a couple horsepower.
