I just bought a 04' 2.9 and I am going though everything to get familiar with it .
I took off the gas tank and fender assy . I checked the antifreeze and it is ok .
I then took out the airfilter that looks like a curved wedge .
The air filter didn't have any oil on it , shouldn't you run airfilter oil on it ?
Is this the only filter or is this some type of pre filter ?
Thanks,
Raz
