UH OH!!! I couldn't resist! AFE just came out with their new Momentum Cold Air Intake System for the C7 that has shown great results (+18whp/+22wtq) and offered it at a group-buy price below dealer-cost, plus threw in a 2nd filter and cleaning kit for me.
I'm unsure when I want to install it, and which filter to use first. I'm leaning towards the Pro5R (blue oiled cotton filter) first then the ProDryS (white dry synthetic filter) once the 5R gets dirty and needs a cleaning.
It's tough to tell from the pictures, but the filters are HUGE! This is probably the nicest intake kit I've ever seen for a car, you can definitely tell a lot of engineering and R&D went into the design of it.
