Me too. I think that NAPA had a few, but you had to make sure that you picked up the right size. as they come in a few different diameters.

 

but you could get a adjustable switch for the fans so that they will not kick on unless it hits 190 or so which would allow it to run a bit warmer.

 

i could, thing is though they dont even run, i was running it pretty hard today up and down some hills hauling a bunch of crap in the bed and they never came on, i think it gets enough air through the radiator just going down the road

 

i love the title of your post.

 

So there's really nothing else I could/should do during the plenum job?

 

You could replace

Timing chain
Water pump
Lifters
Cam
Catalytic converter

 

So the timing chain and cover were done when I has a timing chain gasket leak. Are lifters hard to do and what kind of performance increase does it get me, if any? Or is it more of a preventive maintenance thing? I plan on doing the catalytic converter when I replace my exhaust in January, however it may meet a demise sooner, accidentally....

 

No increase whatsoever replacing the lifters, but you are right there and are ez to do so maintainance thing, around $110 for a set of Mopar performance ones.
