Spoon Venturi Big Throttle Body - Civic FK8,FL5

In recent years of powertrain progress, when tuning for turbo engines that Honda has increased adoption, we considered that turbo engines are NA engines with very high intake efficiency.
This product was born from our idea that "leading as much air as possible to the combustion chamber with less resistance is an important element to efficiently improve the output" gained from the experience of tuning many NA engines so far.
This throttle body increases the output because the flow area can be increased by expanding the butterfly diameter and the amount of inhaled air can be increased.
In addition, by increasing the surface roughness inside the body and lowering the flow path resistance, the flow rate of the inhaled air increases and the response can be improved.
In addition, the intake layout of Honda cars is very excellent even in turbo engines, and in order to maximize its performance, it is also a feature of this product that does not require any processing to the body side from the base of the normal throttle body so that it can be used to make the most of its performance.

Throttle diameter 65.0mm (STD 62.5mm) Area ratio up 8.2%
Butterfly diameter 62.0mm (STD 60.0mm) Area ratio up 6.8%
