I wondered if the EGR valve and throttle body off a MK5 Astra Z17DTL engine will fit a MK4 Z17DTL.
MK4 Part numbers: (from this site)
EGR 97355042
Throttle 97300231

MK5 Part numbers from seller:
EGR 8973550420
Throttle 8973002310

Can anybody tell me if these are the same parts and wil they fit my MK4?

Thanks in advance.
