The Spoon throttlebody is an OE Honda unit that has been taper bored to a 70mm outer diameter. Consequently, the flow-pass area is increased by 16% and the inertial mass during the intake of air is reduced. Engine and throttle response are improved, as is mid and upper rpm power.
A 4-6hp improvement can be expected in the mid-rpm range.
The Spoon throttlebody is a complete replacement unit and includes all necessary sensors.
