I had one in my VP SS and the tempreture went through the roof!!
I had one in my AU2 VCT XR6 ute and the engine definetly breathes better, stopped the engine surging when at idle and had slightly better acceleration.
I did several economy tests with it but it didn't improve the fuel economy in any way. I would recomend them any day over the standard filter and once you have bought it it will last the life of the vehicle, (unless you fit it into your next AU vehicle as I did).
