Cheers guys, am very impressed with how easy the P21 is to apply and how it gives it a deeper shine.
Yeah, the air feeds come with the Viper, although I think you only get one with the package. It was fitted before I bought the car but I think he had to phone PiperX to get another feed. They fit nicely in the fog hole but I'm not sure how the previous owner went about getting the fogs out first!
