Been looking this up and trying to find answers in the archives about sapphires but no good info as yet so;

Will a 2wd throttle body fit a 4x4 inlet
will a 4x4 plenum cover fit 2wd trumpets (any difference between trumpets?)
will a 4x4 cover and elbow fit a 2wd trumpet with 2wd fuel rail
whats the differnce in fitings for a 2 and 4x4 fuel rail if any.
Which is better for throttle response, flow etc Im running 330bhp Phew thanks
