BMW M3 G80 / M4 G82 Titanium Engine Bay Bolt Kit (Grade 5)

Engineered for BMW M3 G80 and M4 G82 owners, this Titanium Grade 5 Engine Bolt Kit replaces the visible steel OEM bolts in your engine bay with show-quality anodized titanium fasteners that are noticeably lighter. CNC-machined in Europe and quality-controlled by BYC Performance, the kit is fully compatible with the original S58 engine block thread pitch and torque values.

If you're building a serious BMW M3 G80 tuning or M4 G82 detail project and want to elevate your engine bay to show-stand level with a functional upgrade, this titanium bolt kit is built for you. The set covers all visible bolts in the engine bay of the S58-powered new-generation M3/M4/M3 Touring/M4 Convertible family (473 hp standard, 503 hp Competition, 543 hp CS/CSL).

Key Features

• Titanium Grade 5 (Ti-6Al-4V): Aerospace-grade material — noticeably lighter than steel OEM bolts with superior corrosion resistance.
• Anodized Color Options: Blue, purple, oil-slick (iridescent), silver, or natural titanium grey — show-quality finish.
• OEM Thread Spec: Fully matches the original thread pitch, length, and torque values of the S58 engine block and manifold studs.
• Engine Bay Coverage: Upper engine cover, oil cap bezel, upper tower bolts, sensor brackets, and visible flange fasteners.
• Weight Savings: Noticeable weight savings across the full set — premium perception focused, not performance.
• Corrosion Resistant: Titanium's natural passivation layer outperforms even stainless steel in long-term durability.
• Track + Daily: Holds up to thermal cycling on both track days and street driving.

Titanium vs. OEM Steel Bolts — Why Upgrade?

OEM bolts are functionally reliable; however, titanium provides a meaningful upgrade in engine bay aesthetics and long-term corrosion performance:

• Weight: Titanium is noticeably lighter than steel (density 4.43 vs 7.85 g/cm³).
• Corrosion: Natural passivation layer is fully resistant to salt, acid, and high-humidity rust.
• Fatigue Strength: Minimal thread wear over many tightening cycles.
• Aesthetics: Anodized colors are stable under UV and heat for years.

Vehicle Fitment

This BMW G80 / G82 titanium bolt kit fits the following models perfectly:

• BMW M3 G80 Sedan (2021, 2022, 2023, 2024, 2025, 2026) — S58 engine (473 hp)
• BMW M3 Competition G80 (2021+) — S58 (503 hp)
• BMW M3 CS G80 (2023+, limited) — S58 (543 hp)
• BMW M3 Touring G81 (2022+) — S58 (503 hp)

• BMW M4 G83 Convertible (2021+) — S58

NOTE: This bolt kit is engineered for the S58 engine bay layout. The previous-generation BMW M3 F80 / M4 F82 (S55) uses a different bolt layout and is NOT compatible.

Technical Specifications

• Material: Titanium Grade 5 (Ti-6Al-4V, ASTM F136)

Installation Notes

1. Turn off the engine and allow it to cool (at least 30 minutes).
2. Remove the OEM bolt to be replaced and install its titanium equivalent (per kit map).
3. Apply the OEM torque spec for each bolt (typically M6: 9 Nm, M8: 22 Nm, M10: 45 Nm — BMW spec).
4. Do NOT use anti-seize compound; titanium is sensitive to it.
5. Once complete, reinstall the engine cover.

Care & Maintenance

Clean titanium surfaces with pH-neutral car shampoo. Never use hydrofluoric-acid-based cleaners. Periodic carbon-safe sealant may be applied for matte finishes.
