Throttle body kit for Honda K20A engines, aluminium alloy valve body sensor with 70mm diameter intake port compatible with performance upgrades and aftermarket modifications in black or silver finish
70mm Aluminium Throttle Body for Honda K20A Engine Performance Upgrades

This throttle body kit provides Honda K20A engine owners with a direct replacement component designed for performance tuning applications. The 70mm diameter aluminium alloy construction offers improved airflow capacity compared to some stock components, with installation designed as a straightforward swap for compatible vehicles. Available in both black and silver finishes, this throttle body serves as a foundational upgrade for enthusiasts seeking enhanced throttle response and engine breathing characteristics without extensive modification work.
Features and Construction

This throttle body kit centres around its aluminium alloy construction and specific dimensional specifications designed for the Honda K20A engine platform.
Material and Build
The throttle body utilises aluminium alloy in its main construction, providing a lightweight alternative to heavier cast iron components often found in stock applications. This material choice maintains the necessary structural rigidity for reliable throttle operation while reducing overall weight in the engine bay. The manufacturing process creates a complete throttle body unit with integrated mounting points designed for compatibility with the K20A engine's intake system configuration.
Size and Practical Fit
With a diameter measurement of approximately 70mm, equivalent to 2.8 inches, this throttle body provides specific dimensions that influence airflow capacity and installation requirements. The 70mm size represents the intake port diameter through which air passes into the engine's intake manifold. This measurement ensures compatibility with the Honda K20A's intake system while offering potential airflow improvements over some stock configurations.
Uses and Placement

This component serves specific functions within automotive modification and engine performance contexts, with clear installation parameters defined by its design specifications.
Event or Professional Use
For motorsport applications or professional tuning environments, this throttle body provides a measurable upgrade path for Honda K20A engines competing in various racing series or performance testing scenarios. The 70mm diameter aluminium construction supports increased airflow requirements for engines operating at higher RPM ranges or with additional performance modifications. Professional installers can utilise this component as part of comprehensive engine tuning packages aimed at maximising horsepower and throttle response.
Everyday Home Use
For automotive enthusiasts undertaking weekend projects or garage modifications, this throttle body offers a straightforward upgrade option with clear compatibility specifications. The direct-fit design for Honda K20A engines simplifies the installation process compared to universal components requiring custom fabrication. Home mechanics can install this throttle body alongside other bolt-on modifications to incrementally improve engine performance without undertaking complete engine rebuilds or complex tuning work.
Benefits and Buying Value

This throttle body provides specific advantages based on its material construction, dimensional specifications, and targeted compatibility.
Reuse and Low Maintenance
The aluminium alloy construction offers inherent corrosion resistance compared to some ferrous materials, potentially extending component lifespan in typical automotive environments. As a mechanical component with minimal moving parts beyond the throttle plate mechanism, maintenance requirements centre primarily on periodic cleaning to remove carbon buildup. The durable construction supports repeated use across multiple tuning iterations or engine configurations.
Why Choose This Product
This throttle body distinguishes itself through specific compatibility with the Honda K20A engine platform and its 70mm aluminium alloy construction. Unlike universal components requiring adaptation, this unit offers direct fitment for simplified installation. The aluminium material provides measurable weight reduction compared to iron alternatives, while the 70mm diameter represents a specific size choice influencing airflow characteristics. The availability in both black and silver finishes allows matching with different engine bay aesthetics.
