Another vote for Volant here. I ran the Volant cold air intake on my '08 JK. Loved it. High quality piece. The volant has a box surrounding the filter with an open slot on the side of the box away from the engine, and a lid that goes on top of the box, to keep out the engine heat. I data logged the PIDs on my JK with the Diablosport Predator and my laptop after installing the Volant intake to get rid of the "hot air" argument may had on another forum. My IAT temps were unchanged. They were actually almost 2 deg cooler, but that could've been from a few variables, not enough difference to call it cold air. Granted a lifted JK has more air flowing through the engine bay from underneath, because of the removal of the air damn, and higher suspension with a 3" lift. But mine did not suck any hot air. Now the intakes like the AEM and a few others that have a 100% exposed open air filter, sure, that thing is sucking hot air for sure.
Here is my Volant intake on my JK. Mostly covered, with a slot for air intake.
Is the Volant intake for the WK2 a similar design? Or did they change it?
