I have that Calmini setup on one of my vehicles. It is a nice unit for the money. You can always add a Green filter to the Calmini if you want to improve filtration. I am not sure there was much performance gain, but I like the cone filter sound. True to Tone's observation, it could benefit from some sort of heat shield. Due to its design, the intake is both higher and farther back in the engine compartment (nearer the hot engine and hot air) than some of the other designs I have seen. That said, I am looking forward to trying one of the Green intakes sometime soon. You could always try the Green drop in. If you are not happy with it, another member might take it off your hands. Good luck.
