Upgrade your 2JZ-GE cooling system with our all-new CNC-machined billet aluminum upper water neck, engineered for superior performance, durability, and aesthetics.
 
Designed as a direct replacement for the OEM cast unit, this billet neck not only modernizes the look of your engine bay but also adds enhanced functionality.
 
Key Features:
 
Integrated Sensor Port Options:
Accepts a range of sensor threads including M12x1.5 (OEM), 1/8-NPT, and others — giving you the flexibility to mount your temperature sensor directly into the neck.
 
ORB-Threaded Outlet:
The outlet is machined for ORB fittings, allowing seamless connection with our ORB-to-AN adapters. Choose between barb fittings for OEM hoses or upgrade to -16AN / -20AN hose ends for a full AN setup.
 
Optimized Fitment:
Slightly shorter than the OEM piece to maintain OEM-equivalent total length once your chosen fitting is installed.
 
VVTI Compatible:
Specifically designed to retain the VVTI line mounting point, ensuring a perfect fit and a clean factory-style installation on all 2JZ-GE VVTI engines.
 
Premium Billet Finish:
Machined from high-grade 6061-T6 billet aluminum, offering exceptional strength, corrosion resistance, and visual appeal.
 
Custom Anodized Finishes:
Available in all anodized colors, allowing you to match your engine bay theme or create a standout custom look.
 
Don’t wait to upgrade — transform your cooling system with the precision and reliability your 2JZ deserves.
 
Note: Sensor not included but available separately.
