The E46 CSL M3 is world renowned as one of the finest cars BMW produced. Covered with parts exclusive to the CSL model, the intake system is one of the most sought after components for non-CSL owners. The performance rewards are just as great as the sound, a true symphony to an enthusiast's ear.

The Turner Motorsport CSL Style intake takes the legendary BMW design and improves it, by altering and improving the OEM CSL airbox we have achieved a 20% increase in airflow of the factory airbox and also marginally improved flow over the BMW designed CSL box!

This complete kit includes everything (except a tune) to completely transform your M3 is a afternoon.

*Will require use of a Alpha N tune*

NOTE: For US vehicles with a production date of 09/2004+, the original PCV recirculation hose will need to be re-used and modified. The included silicon hose will need to have one of the included fittings removed and then be spliced into the factory PCV hose to retain PCV functionality. If you would like a silicone hose without fittings pre-installed, see ES4504787.
