2008 BMW Z4 Valve Cover and Cylinder Heads

Cylinder Head Bolt Set

Using new head bolts when performing a cylinder head installation is always a good idea however, on late-model engines that came from the factory with TTY (torque-to yield) head bolts, replacement is an absolute necessity. TTY bolts are designed to exert the maximum clamping force for a tight head gasket seal, however they permanently stretched and could fail if re-used.

Product Features:

Approved materials for increased durability in even the most extreme temperatures. All MotoRad Coolant Temperature Sensors are designed to meet or exceed OEM specifications at our ISO TS16949 manufacturing facilities.

Product Features:

• 100% factory resistance calibrated to ensure precision tolerances, resulting in extremely accurate temperature for optimal performance
• Thread Sealant and/or O-ring pre-installed on applicable sensors to ensure leak free performance
• Brass sensor housing precision machined to meet or exceed OE thermal conductivity
• OE precision matched thermistor position for correct output parameters
• Extensive product testing includes salt spray, high/low temperature impact, thermal vibration, durability, static electricity, and micro tension, among other tests, to ensure all sensors meet or exceed OEM specifications.

TRW Engine Components is a recognized developer of valves and valve train components. A wide range of materials and material combinations are used to meet the engineering requirements in the different engine applications. Materials vary from ferritic martensitic steels (intake valves) and austentic CrMn based steels to extreme heat and corrosion resistant Nickel base super alloy for exhaust valves. To improve wear and corrosion resistance, valves can be chromium plated or nitrided. These coatings are used to improve the compatibility of the valve stem surface to the valve guide material. If necessary, exhaust valves (and in some cases also intake valves) can be hard-faced. In hard-facing, a more heat and wear resistant material is welded to form the valve seat. Seat hard-facing extends the valve life significantly.

Product Features:

• OE Quality
• Optimized for strength
• Heat and corrosion resistant
• Chromium plated or nitrided
• Stem optimized to resist wear
