ARP BMW E30 325i/is/iX 1987-1991 Head Stud Kit (2.5L) - 201-4305
$271.18
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1987-1991 BMW 325i, 325is, and 325iX models equipped with the 2.5L M20 6-cylinder engine.
The ARP 201-4305 Head Stud Kit is a critical upgrade for the BMW M20 engine, providing significantly more consistent clamping force than factory stretch bolts. By utilizing studs rather than bolts, this kit ensures accurate torque loading and protects the engine block threads from wear during assembly. This is an essential installation for any high-performance E30 build to prevent head gasket failure under increased cylinder pressures.
- Manufacturer Part Number: 201-4305
- Engine Fitment: BMW M20 2.5L 12V SOHC
- Includes high-strength head studs, parallel-ground washers, and 12-point nuts
- Replaces factory torque-to-yield (TTY) head bolts
- Reusable fasteners for easier top-end maintenance
