Clio 172 Cup
tried to take my K&N filter back the other day, want a viper instead. Its been on my car for about a month. Didnt notice any real increased performance. So i told em that at the shop. The guy was a right mother f**ker..... he laughed in my face and said i dont think K&N will refund the money because YOU dont notice any performance increase. He said come back monday when someone from the technical dept is in. I had a go... said well its false advertising to say there is an increase in power, but there isnt. He got stroppy. I told him a load of sh*t about having a roling road before and after and that it proves there is no increase in BHP. Said i was gonna bring the results in and show him, but i aint got none!!! Never had a roling road. sh*t! Wat can i do?? Help!!!!
