Looking for an inlet manifold and throttle body

What options are there in terms of inlet manifolds and throttle bodies for the 2009 1.8l NC? The only one I can find costs £1100 and is the giselworks intake manifold.

There’s a skunk intake and throttle body for both the NA and NB models though I can’t seem to find one for the NC. There doesn’t seem to be as much mod support for this version compared to the older models.

Jenvey do an ITB kit for the nc, you would need an aftermarket ecu and tuning. Mazda Mx-5 NC DTH 45mm kit

There aren’t any cheaper options?
