mgf airbox; it has a rounded top and 7 longitudinal lines running along the lid. This is the smaller type of airbox and has a resinator underneath.
mgtf airbox; it has a more angular airbox top with 5 longitudinal lines running along it. No resonator. If this is the one you havelook inside it to see what connections you have. With the engine panel removed you can see if there is a front hose anyway.

I quote Roger Parker - mgf and tf restoration manual page 252 'A useful pointer regarding fitting a throttle body is that there is often a noticable improvment in engine smoothness from having the throttle stop balanced using dealer t4 or gds diagnostic equipment.'
