My mate just bought a st170 and is considering buying upgraded throttle bodies for it.

they function by opening a flap and letting more air in.... same as any TB, but the inlet manifold is shorter with a TB for each cylinder, rather than 1 TB into an inlet manifold, then to 4 cly

so...

its changed to 4 to 4, from 1 to 4 assuming 4 pot engine

The increase they power, but need standalone management, prob some fueling hardware mods, and the noise is very obtrusive.

Surely it won't have independant throttle bodies as standard?
