value of a decent phase 1 172 airbox?

[m4tt274]

When i bought my 172 it has a K&N filter/ktek replica type setup on it.

Im interested in returning it to standard/oem which brings me neatly to an airbox query.

People have mentioned that an espace airbox is a good upgrade, could anyone share any light on these.
Also, is the phase 2 172/182 airbox better or more desirable to the phase 1 standard airbox and pipework?

How much will i be expecting to pay for a decent standard airbox setup, TB back?

Thanks, Matt.

About £30 for a secondhand one.

I sold mine for £35 delivered!
Good condition all clips in tact. I think people are daft asking for £50
