Installed a Airaid CAI a few weeks ago. I've been running it for some now with a Pre-Filter installed and access plate off for a while. At some point I will remove the Pre-Filter and install the access plate to see what kind of difference there is.
Mounted my flashlight/axle/ Halguard 2.5lb fire extinguisher last weekend to my Vector Offroad MP Table. I used some Quick Fist mounts for the axle and flashlight.
I also got my Rigid D2's installed using their new bumper adapters that allow you to mount D2 were ever a stock bumper light will fit.
Speaking from Offroad fire rescue experience, that 2.5lb bottle won't amount to much in the event of a car fire - large or small. I'd recommend a larger bottle in addition to that 2.5lber. It's gotta be accessible FAST.
