Detailed Description

Elring 794.470 is a direct-fit engine cylinder head bolt set engineered around the listed BMW fastener specification: female Torx drive, M11 thread size, 1.5 mm pitch, and 188 mm length. That combination matters during cylinder head service because the bolt design, thread pitch, and length must match the engine’s original hardware requirements for proper clamping and assembly.

Compatible With BMW 220i, BMW X3, BMW X4, BMW 420i Gran Coupe, BMW 530i, BMW 530e, BMW 740e xDrive, BMW 740Le xDrive, BMW 330i, BMW 430i, and BMW Z4 applications shown in the fitment data. The Elring 794.470 part number is also useful for buyers searching by OE-style engine hardware specifications rather than by vehicle alone.

What This Part Helps Address

• Worn or stretched cylinder head bolts during engine repair
• Incorrect fastener length or thread pitch during reassembly
• Female Torx drive mismatch with the original bolt design
• Loss of proper cylinder head clamping after head service
• Fitment issues when replacing BMW engine hardware by specification

Installation Notes and Tips

Verify the engine’s original bolt specification before installation, including M11 thread size, 1.5 mm pitch, 188 mm length, and female Torx head design. Clean the threaded holes and mating surfaces before assembly, and follow the BMW service procedure for tightening sequence and torque steps. Because cylinder head fasteners are critical engine hardware, confirm application details against the vehicle’s engine code and service information before installation.

Quality Assurance

Elring is a recognized name in engine sealing and hardware applications, and 794.470 is built to match the listed BMW fastener requirements for accurate service replacement.
