Re: CAI 2015 Jeep Grand Cherokee Altitude
Most CAIs are in reality Hot Air Intakes.
I made my own snorkel that combines the benefits of a "ram air effect" and that of a cold air intake (i.e. its inlet port is OUTSIDE of the car, forward facing in the direction of travel). I have added benefits of 2-3 MPGs over stock and added power, as measured on private closed roads in side by side contest against a similarly engined but lighter (no skid plates = 100 lbs ?) Overland . The guy is here on the boards and he'll attest that in a 40-70 mph sprint, I would consistently be ahead by almost a car length.
