No-nonsense guide on replacing spark plugs and ignition coils in the 1.6thp engine found in Citroen, Peugeot, and Mini.
You will need:
Torque Wrench
14mm Thin-walled Spark Plug Socket
New Plugs
New Coils
Spark Plug Gap tool if your plugs aren't pre-gapped

I have found the cheapest way to do this job is with parts from RockAuto, but your mileage may vary. I used:
BOSCH 9710 #ZR7SI332S Spark Plugs
BOSCH 0221504800 Ignition Coils

Spark plugs should be kept no more than 30,000km on a completely stock engine. If you have a remap, it is advisable to renew them every 20,000km because you will notice a big drop in performance as you go over the 20,000km limit.
A good way to check their condition is by measuring spark gap. Stock spark gap is 0.8mm. The moment it goes over 0.9mm, ignition problems start to occur. For engines with a remap, we recommend setting the spark gap to 0.6mm. This will increase spark plug wear but will improve spark power by a lot. Only the heat range of Platinum and Iridium is suitable for turbo engines.
Useful codes:
Iridium – ILZKBR7A-8G (Peugeot RCZ THP200, Citroen DS4 Racing THP200, Mini Cooper S Works Edition)
Platinum – PLZKBR7A-G (stock 150/156/165hp and 175hp)
