There is no ignition capacitor.
There are distortion capacitors
I placed mine at the +contact near the module and one at the B+ on the alternator.
The ignition module for 1.6 and 2.2 are different.
The 1.6 has a Hall module driven by a hall sensor in the distributor
The 2.2 has a induction module driven by a coil also located in distributor.
The module in the above link is wrong.
Stated in the auction is that they can be used in 1.6 and 2.2 wich is impossible.
For the 2.2 you need the Peugeot 2.2 turbo module.
Bosch nummer for the 2.2 confirmed working 0227-100-123
