Like the title says. I installed a Takeda stage 2 cold air intake last night. So far I'm liking it. You can hear a slight growl under the hood now when you give it some gas. Install took under an hour with simple hand tools. 10mm socket and a Philips screwdriver. Supposedly it can have gains up to 6 extra hp, but we all know that has to be under perfect conditions. Does have a tad bit extra throttle response though, and I can hear it, so I'm happy!
