The new GPF filter from the Volkswagen group reduces particulate emissions from petrol direct-injection engines by 90%. P-Tronic has already developed the tuning box to fit models equipped with these filters, offering total compatibility. The first served by this GPF are the VW Tiguan 1.4 TSI at 125 and 150 hp and the Audi A5 2.0 TFSI at 252 hp. The filters were fitted from June 2017. The other petrol models from the VAG group will gradually follow, with the aim of fitting this system, more affordable than the FAP, in no fewer than 7 million vehicles by 2022.
