The 1JZ intake manifold is designed for Toyota’s 1JZ-GTE and 1JZ-GE inline-six engines, optimizing airflow for improved horsepower, throttle response, and overall efficiency. Constructed from high-strength aluminum, it ensures durability and heat resistance, making it ideal for both stock and high-performance applications. Many aftermarket versions feature a larger plenum and smoother, longer intake runners, improving air distribution, especially for turbocharged setups. Designed for EFI compatibility, these manifolds allow seamless integration with factory or upgraded fuel injection systems. Available in direct-fit and custom configurations, they can be used for street, drift, and racing applications, often requiring minimal modifications for installation.
