ST170 Inlet
 

does the ST170 inlet manifold flow better than the High Flow alloy inlet found on the 130 specs?

what's the application? flow wise it's pretty good (dependent on runner position vs rpm), but doesn't take boost well.

Silver top 1.8 Zetec, with cams, ported head, omex and uprated exhaust

the shitter is i had one in the shed but think my old dear may have slung it out, i got the throttle body for definate but will check manifold

are you experiencing symptoms of inlet restriction e.g. torque flat-lining at higher rpms? if not i wouldn't bother as you'll need the imrc box connecting up to your omex to make the most of it.....
