One of the first things I did when I got my pop charger on my Frontier was to fab a shield for it to keep out some of the heat from the motor. I also routed some piping to draw cooler air from outside. When I did the shield, I tapped a hole for the sensor placing it near the filter. Later on, I completed the project by making an intake tube. You can see pics of it all here and maybe you can figure something out that will work for you. www.picturetrail.com/ecujeb
