This is the Genuine BMW radiator for SULEV E82 128i and E90/E92 328i models. SULEV is the Super Ultra Low Emissions Vehicle status used in California, New York, Massachusetts, and some other states. These are the cars with the N51 SULEV engine, which was the lower emissions variant of the N52 engine. 

The N51 manual Genuine BMW radiator includes a special coating that converts ozone into oxygen. This coating helped BMW with California emissions certification and the coating is required for all replacement SULEV radiators. The radiator actually has a compliance sensor fused to the back of the radiator to ensure the coating is applied and active, as well as feeding coolant temperature information to the engine computer. A new sensor is included on this radiator. Using a non-SULEV radiator without the coating will trigger a fault code and check engine light. Unfortunately, the sensor is not available separately from BMW and is not easily removed without damaging it.

The good news is that a failure in the N51 SULEV radiator or the sensor may be covered under the vehicle's emissions warranty. Before committing to a new radiator, check with BMW or your dealer if you're covered. If your radiator is no longer covered by the warranty we have the new Genuine BMW replacement at a substantial savings from list price and it comes with a factory two year warranty.

For manual transmission models ONLY (not for automatic). 

A new drain plug (control sleeve) is not included with the radiator and is sold separately (see below).
