Red one is $109, Yellow 159, and Blue $134 (clearance) at PepBoys. I've notived that red has more cold crancing amps then yellow as well as longer replacement (3 years vs. 1 for yellow)

Any suggestion which one to get. I've seen red ones in Costco for $99. Website of Optima is not very informative on sizes, fitting etc.

Any suggestions ?

thanks
