As many E36 enthusiasts know these header are the best flowing headers for the e36 available with proven dyno testing compared to the other headers available for E36 engines they add estimate 10hp and good amount of torque especially on the S50 engines.

Headers were installed on a 1995 S50 M3 for 2k miles and were removed when the car was swapped with an s54 engine. When they were Removed the headers were coated with a thin layer of WD-40 to help with corrosion and surface rust buyer can clean it before installation or install with the coating on and it will burn off as the exhaust gets hot. Headers come with gaskets which we do believe to be S50 specific gaskets but we have not tested it on an s52 to confirm fitment therefore we can not guarantee fitment of the gaskets on the S52s engines. They also come with 24 studs and 24 exhaust nuts.

Headers do have the bungs for the S52 OBD2 Oxygen Sensors as well
