I've seen the dyno run that shows the R2C making the same peak power as the Stillen G3. While this may very well be representative of actual performance, I don't think a dyno is a good test for a CAI. Measuring IAT vs ambient while driving seems to be more meaningful. 5 to 10 degrees above ambient has been achieved with either system, especially when coupled with fang vents. The quality of the filtration is much better with the R2C as is ease of access and install. On this board the Stillen G3 seems quite popular where the R2C is more favored with the G37 crowd. I'm going to measure IAT with the stock intake first, then do fang vents and measure again. If I get IAT's 5 to 10 degrees above ambient then the stock intake will work for me. Otherwise I'll try the R2C mainly because of its superior filtration capabilities. My 370Z should be here in a few weeks.
