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.
Recommended For
Aftermarket header installation
Exhaust manifold replacement
Broken, seized, or corroded manifold hardware
Engine rebuilds and restorations
Turbo and supercharger builds
High-mileage Nissan and Infiniti VQ applications
Fitment

Infiniti Q50
Infiniti Q60
Important: VQ35DE, VQ35HR, VQ37VHR, AWD, model-year, factory-manifold, and aftermarket-header configurations can differ. Confirm compatibility with your exact vehicle, engine, and header setup before ordering.
Tools Required
4 mm hex bit for manifold studs
9/16-inch 12-point socket for the supplied manifold hardware
12 mm 6-point socket for the lower two bolts
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.
