If you want to buy a left handed screw driver OR a cold air intake for your Jeep you should try:
Mopac Auto Supply Ltd
130 16 Ave NW
Calgary, AB T2M 0H2
(403) 277-0101
Cost, liability, and filter maintenance of a CIA far outweighs any performance increase whether it be real or perceived.
Save your pennies now, you'll need afford filling up your rigs this summer....
