Clio 182, OctaviaVRS
Just found this - but does anyone know what they are, where they go etc? Heres the description:
These kits consist of a JR Element and a performance petrol pressure regulator.
The regulator is fitted in place of the original, very simple, very quick. When fitted the regulator will increase the petrol pressure to the injectors (e.g. from 2.2 bars to 3.5 bars). The result is better atomisation of the petrol in the cylinders.
