Petrol engines also now have PPF’s (I don’t know if they are yet compulsory but they are here) - petrol particulate filters and my Mini was one of the last petrol engined Minis built before BMW started fitting them and JLR is now fitting them to their petrol engines - it is one of the causes of the 2019 SVR’s having significantly quieter exhausts compared to the previous generations of that model, so could also be called a NPF - Noisy Particulate Filter! 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
