The V6 is great for highway miles, I think I get best mileage if I set
the cruise control at about 75-80mph and leave it there.

This goes very well with the K&N panel filter, and probably the throttle
body mod (I'll know if I ever get one.......).  I think that the intake
tube is probably one of the smallest parts of the whole system.  I've
got a setup right now using a 4" polypropylene dryer vent hose and a 4"
-> 3" ductwork converter...I think there's a brief writeup in the 12v
I think that the 12v's air intake setup really kills it; looking at the
engine training booklet I see a couple of things that could be tweaked
to make it more efficient...someday when I have time (yea right) I'll
try poking around with a few things.  In the meantime, a K&N + this air
intake tube really helps it out between about 3000-3700rpm's.  A
worthwhile mod for 12v owners, especially since it's very cheap!

BTW, people are welcome to make submissions to the 12v pages, including
data!  Someday I plan to sit down and make the site marginally useful to
people with cars besides the 90.

That's OK, I probably won't have time to get to it until Feb-March
