SPDZ1 VQ Header Installation Kit – MLS Gaskets & Titanium Hardware | 350Z, 370Z, G35, G37, Q50, Q60
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.

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

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.

Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
