Replace the factory fasteners in the engine bay of your BMW G80 M3 / G82 M4 2021-2026 with titanium bolts, nuts and washers using the TiHex titanium engine bay kit. The kit gives different areas of your engine bay a consistent finish.
The titanium parts are CNC-machined from Grade 5 titanium (Ti-6Al-4V). This material combines low weight with high strength and excellent corrosion resistance. Every titanium part is polished by hand. Coloured finishes are then anodised by hand in your chosen colour.
Choose socket head bolts with Cup Washers for a bold look with more exposed titanium, or low-profile Torx bolts with Step Washers for a lower, cleaner profile.

Bare Titanium has no anodised layer. Anodised finishes are applied in your chosen TiHex colour after ordering. PVD Blue is a PVD finish, not an anodised colour.
Anodised titanium can show small colour differences due to surface finish, product shape, lighting and viewing angle. Screens may display colours differently. Small differences between anodised parts are normal.
Before installation, check that size, thread pitch, length and version match the original fastener and suit the application.
Use the correct tools and avoid damaging threads or the product.
For safety-critical or highly loaded connections, including brakes, suspension and steering, follow the vehicle or component manufacturer's technical specifications and torque settings.
If you are unsure about suitability, contact TiHex before ordering.
