Purpose-built for BMW N54, N55 and S55 engines, this titanium bolt kit is a direct-fit replacement for the factory oil thermostat bolts and is designed to pair perfectly with Mosselman N54, N55 and S55 oil thermostats. Strong, light and highly resistant to heat and corrosion, these Grade 5 titanium bolts provide a dependable, long-lasting solution for fast road and track use on popular BMW models including M135i, M235i, 335i, 435i, Z4 35i, M2, M3 and M4.
We run these Mosselman titanium bolts on our own builds and customer cars. Feedback has been excellent, with crisp torque feel during installation and long-term reliability even after repeated heat cycles.
