does any one know the cloest refill station to tri-state raceway in iowa?

------------------
1988 Firbird Formula 350
150hp NX kit, Air Foil
K&N, Jet Stage 2, 8mm wires, MSD 6AL, Trailing Arms, Panard Bar, 3" Ex. with cut out instead of cat. 5" tach.

e.t.= none yet
mph= none yet

 

If you go onto NOS's site. they have a 800 number you can call that gives you the closest re-fill stations. I think you can look it up on their site too.
