For $1000 I would buy an Alpina airbox assembly...but it probably costs even more than this...and it probably is not available if you don't have an Alpina car  |

Depending on availability in your area and assuming a favorable exchange rate, you might want to take a look at a Dinan cold air intake, $1300US, as a nice alternative to the Alpine unit.
