Also its placement seems to act as a spacer for the primary filter when you snap the fasteners.
Anybody on this. I am just assuming the next white looking filter, with aprox. 6 plastic rivets holding it, in the airbox right by the primary filter is indeed the secondary we are talking about.
I am not sure I am following you here.
The AFE filter is not quite half as short front to back as the stock paper filter is. How could the afe filter be almost hitting if the stock filter doesn't. I had no problem installing mine, and everything fit correctly. A buddy has my truck right now as he is moving this weekend, or I'd go take some pictures for you.
Also there have been no engine changes made to the 4.0 from 05 to 08, the only difference has ever been that the octane of the test gas was changed and that is where the lower horsepower and torque numbers come from.
Any yes the white charcoal impregnated filter heald in by 6 plastic rivits is the secondary filter.
