Is that needed on my rig? Or should that have been removed for the desmog? I did a little looking and saw some pics how that is plumbed in. Guessing it just "recycles" exhaust for another attempt to burn it up. Hot exhaust goes into the cooler and the fins dissipate heat. Then the "cooler" gas is sucked into the intake when the valve is opened. Does the valve open at certain rpms? Or is it disabled since my engine has been desmogged?
