The Permanent Solution to Seized & Snapped Manifold Bolts
If you are upgrading your headers or performing maintenance on a Porsche 991, you likely know the reputation of the factory hardware. The original steel bolts are notorious for seizing into the cylinder head, often snapping upon removal and turning a simple job into a costly repair.
Our Grade 5 Titanium Manifold Kit completely rectifies this problem. Titanium is naturally resistant to the galvanic corrosion that causes steel bolts to bond to the aluminium head. By replacing your OEM hardware with this kit, you ensure that your manifold remains secure and, crucially, that it can be removed easily in the future without the risk of snapping.
Why Upgrade to Titanium?
Zero Corrosion: Unlike OEM steel, our Grade 5 Titanium will never rust or seize, preventing the "snapped stud" nightmare.
Superior Strength-to-Weight: Aerospace-grade materials that handle the extreme heat cycles of a high-performance Porsche engine.
Ease of Maintenance: We’ve paired these studs with 10mm hex copper K-Nuts. The smaller 10mm head provides much-needed clearance when installing bulky aftermarket headers where space is at a premium.
