emailed the company Jesske mentioned I think there from Belgium
www.cliosport.org. Got a reply within the hour! I was asking what he thought about the cup intake arrangement vs. the viper.
"I have to check the up to date price for a few people already. I sold many of these, but because of the new RS, prices are changed. I will inform you asap
I can tell you that it won't give you more performance than an ITG filter and that ITG is much better quality. You have to keep in mind that everything they use in Cup is as standard it can be, because they don't care if it's broken the first or second time, they just put another one in it. That means quality is not allways as good as an aftermarket product. I know many tuners love the Viper besides the ITG, but we measured powerlosses in some rpm ranges with the Viper. The ITG is absolutely the best filter you can get
If you want my honest opinion, I wouldn't do this mod because you won't notice the difference with the changes you already did. You've spent lots of money on your mods and if I were you, I would spent my money on an ITG"
So a maxogen is better then a viper for power according to him and dont bother with the cup car bits. Pretty helpful and honest really.
