Aluminium alloy throttle body valve sensor for Honda K20A engine conversion and performance tuning, 70mm black or silver finish high-flow air intake modification part.
70mm Aluminium Throttle Body for Honda K20A Engine Conversions and Tuning

This throttle body serves as a core component for modifying the air intake on Honda K20A engines. Engine builders and performance tuners seeking a reliable, direct-fit replacement or an upgrade from the standard unit will find this 70mm aluminium body provides a solid foundation. Its specification is geared towards supporting increased airflow for engine conversions, revitalising older engines, or as part of a broader performance induction system, with a choice of two practical colour finishes.
Features and Construction

This component is built with a focus on direct application and material suitability for high-performance engine bays. The design prioritises fit and function over unnecessary complexity, making it a straightforward choice for targeted upgrades.
Material and Build
The throttle body is constructed from aluminium alloy, a standard material for this type of component due to its favourable properties. Aluminium offers a significant reduction in weight compared to ferrous metals, which is beneficial for overall vehicle weight distribution and unsprung mass. It also provides inherent corrosion resistance, helping to maintain the unit's integrity and appearance in the often harsh environment of an engine bay over time. The machining of the 70mm bore is a critical aspect, as it directly influences airflow characteristics into the engine.
Size and Practical Fit
The key specification of this product is its 70mm (2.8 inch) diameter. This measurement refers to the internal bore through which air passes into the intake manifold. It is designed as a direct fit for the Honda K20A engine, meaning it should bolt directly to the standard intake manifold mounting flange, simplifying the installation process. This precise fitment is crucial for avoiding air leaks and ensuring the engine management system receives accurate readings from associated sensors.
Uses and Placement

This throttle body finds its primary use in specific automotive engineering contexts. It is not a generic accessory but a functional part intended for particular projects and repairs.
Event or Professional Use
In professional or competitive environments, this component can be part of an engine rebuild or performance upgrade for Honda K20A-powered vehicles. It is suitable for track cars, time-attack vehicles, or any build where a known, reliable throttle body is required. Its direct-fit nature saves fabrication time, allowing mechanics and builders to focus on other complex aspects of the conversion or tune.
Everyday Home Use
For the knowledgeable home mechanic or enthusiast, this throttle body is a solution for two main scenarios. Firstly, it can replace a worn, damaged, or faulty original throttle body on a Honda Integra Type R, Civic Type R, or other K20A-engined car, restoring proper throttle response and driveability. Secondly, it can be used as part of a planned engine swap or performance modification project in a garage, providing a new component of known quality and specification.
Benefits and Buying Value

The value of this product lies in its specificity and material construction. It addresses clear needs within a niche market, offering a practical rather than an extravagant solution.
Reuse and Low Maintenance
As a machined metal component, the throttle body is designed for long-term use. The aluminium alloy construction resists corrosion, and there are no complex internal electronics within the unit itself that are prone to wear. Its durability means it can potentially outlast the engine it is installed on and be transferred to another build, provided compatibility is maintained. Maintenance typically involves only periodic cleaning of the throttle plate and bore.
Why Choose This Product
You would choose this throttle body if you require a direct, bolt-on component for a Honda K20A engine. Its primary advantages are its confirmed compatibility, the choice of black or silver finish to match an engine bay theme, and its construction from appropriate automotive-grade aluminium. It eliminates guesswork regarding fitment and provides a solid base for induction system tuning or reliable daily driving.
