Product Detail
Specification:
Intake Diameter:Φ34
[Description]
Spigot Outer Diameter :40mm
Spigot Length :24mm
[Separately required parts for installation]
Either of the following throttle holder sets
・Yoshimura Racing Throttle Holder Set for TMR Small Body (L=750mm)
・Yoshimura Racing Throttle Holder Set for TMR Small Body with Switch (L=750mm) (Switch side coupler wiring needs to be changed)
[Parts required separately]
・Yoshimura Oil Breather Tank Kit (Funnel type and BMC filter type are required.Not required for the Stock cleaner box specification.)
[How the DUAL STACK works]
The DUAL STACK Funnel is designed to provide the performance of both the Short Funnel and the Long Funnel plus alpha.Each funnel does not work only in its own area, but each funnel brings synergistic effect to each other, which leads to the improvement of combustion efficiency, in other words, the improvement of performance.
■In the case of low opening range
・1st funnel:
In addition to the rectified air inhaled from the 2nd funnel, it assists the intake of +α of negative pressure.This allows more air to be drawn in and burned than would normally be the case, leading to an increase in power output at low engine speeds.
・2nd funnel:
It acts as the main funnel and draws in rectified air.
■At full throttle
・1st funnel:
It acts as the main funnel and quickly draws in the necessary amount of air for combustion.
・2nd funnel:
Due to the negative pressure caused by the 1st funnel intake, the rectified +α intake air is assisted.This allows more air to be taken in and burned than would normally be the case, leading to an increase in power output at full throttle.
