clio ph1 parts on ph2?? help~

[Nikke Tse]

i read on wiki that there are some differences between them (172 ph1 and ph2)
i wonder if i can replace the cheaper parts of the 172 ph2 (airbox, filter, Lambda sonds) to the ph1's airbox, filter and catalytic converters.

thanks =]

The airbox will fit but the cat wont as it's a different length or fitment one of the two. Why would you want to change cats anyway?
