Bosch like most manufactures produce of range of equivalent spark plugs to NGK. Manufactures tend to sign a deal with a spark plug manufacturer and that is how a particular spark plug brand is officially listed as an OE part. For the Peugeot 208,RCZ, 308  and Citroen DS3 1.6T range NGK is the official brand however Bosch produce a spark plug to the same specification.

 

Spark plugs play a vital role in the cylinders of your engine. When plugs ignite the fuel in the combustion chamber they then help to transfer the heat from the cylinder into the head and out of the engine. This is why you see spark plugs that have a different heat operating ranges. As you increase the boost on a modified turbo engine the air entering the chamber will be hotter so you have a hotter combustion cycle which requires more heat to be removed so to stay with a healthy operating temperature. When the exhaust gas temperature is extremely and since the ECU is monitoring this the car will add fuel into the process to keep things cool enough, there’s a point when it cannot add more fuel (or enough of it) so fitting the right spark plugs for your level of tune is important. Generally around stage 2 things are getting pretty hot for spark plugs and at that level of modification it can be a good idea to fit colder spark plugs.
