It’s time to take your 4G63 platform to the next level. Introducing our Full CNC-Machined Billet Intake Manifold, engineered from the ground up to deliver uncompromising performance for the legendary 4G63 engine.
This isn’t just another fabricated manifold — it’s the result of over 10 design iterations, extensive CFD simulations, and real-world testing, refined to achieve the perfect balance of airflow, durability, and efficiency.
Key Features
2-Piece Billet Construction – Precision-machined from 6061-T651 aluminum for maximum strength and reliability.
Multiple Throttle Body Options – Available in Bosch 82 mm and Bosch 74 mm bolt patterns. For Other patterns please contact us prior to ordering.
Fueling Flexibility – Choose single or dual fuel rail configurations to meet any power goal.
OEM Compatibility – Retains factory fuel rail mounting points, making it compatible with leading aftermarket brands like Radium, Ichiban, and others.
Performance-Driven Design – Optimized specifically for the 4G63 using CFD technology to maximize airflow and cylinder distribution.
Unlike manifolds pieced together from multiple welds and components, this billet solution provides seamless flow, unmatched durability, and a clean professional look worthy of your build.
If you demand a manifold that performs as good as it looks — this is the one.

Reviews
The ichiban engineering intake manifold is not only stunning, the internal runners are super smooth ready for response. I have a 68mm Bosch dbw using their 82-68mm adapter they sell separately. There is no issues bolting up the radium fuel rail and using ID1750 injectors. I have an aeroflow billet adjustable dipstick which moves the dipstick to above the alternator easily accessible.
