QED Direct to head throttle bodies

Direct to head is the ultimate in throttle body evolution. There is no longer a need for seperate bodies mounted onto an inlet manifold. Direct to head offers a simple efficient fitment.

These purpose designed bodies have an almost parallel 45mm bore leading to the butterfly followed by a gradual taper to match the inlet ports.

Typically these bodies house a single injector per cylinder but can be supplied with an additional injector mounting for high volume fuel delivery (e.g. methanol burning engines).
