Frequently Asked Questions
Complete VQ Header Installation Kit
Everything needed to install or replace VQ exhaust manifolds and headers without reusing old, rusted, or heat-cycled factory hardware.
The SPDZ1 VQ Header Installation Kit combines heavy-duty multi-layer steel gaskets with a complete titanium exhaust hardware set. It is designed for performance builds, header installations, manifold replacement, turbo or supercharger projects, and high-mileage VQ engines where factory hardware may be seized, corroded, or no longer suitable for reuse.
Why This Kit Is Different
- Complete installation solution: gaskets and premium hardware in one package
- MLS sealing: multi-layer steel construction for improved heat resistance and long-term sealing
- Titanium hardware: strong, lightweight, and highly resistant to corrosion and heat cycling
- No reused factory hardware: ideal when installing headers or replacing manifolds
- Performance-ready: suitable for stock, naturally aspirated, turbocharged, and supercharged builds
Kit Includes
- (2) MLS exhaust manifold gaskets
- (2) MLS two-bolt exhaust gaskets
- Full set of titanium exhaust manifold hardware
- Matching titanium installation hardware
All included components are shown in the product photos. Hardware quantities and configuration should be verified against your exact engine, exhaust manifold, or aftermarket header application before installation.

Installation Note
Exhaust manifold access is labor-intensive on many VQ platforms. Professional installation is recommended unless the installer has the proper tools and experience. Use appropriate high-temperature anti-seize where required and follow the correct torque procedure for the vehicle and installed header or manifold.
