Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

For the US E36 M3. Schrick 264/256 degree camshafts boost mid-high end power for that extra motivation at higher rpm. Low-end torque is not seriously affected due to the M50/M52s VAN0S System. And, higher profile cams work extremely well with an upgraded intake and exhaust. When upgrading the cams there are other areas you must take into consideration. Higher-flow fuel injectors, larger mass-air sensor, and custom programming are strongly recommended. Turner Motorsport sells complete intake & cam packages that boost power to over 290hp. See the Engine section under Camshafts for more info.
Cam Specs:
Intake - 264 degree, 11.2mm lift
Exhaust - 256 degree, 10.6mm lift
