if you live in a warm climate you can go with the odyssey or the braille 2015. i would recommend the braille because the specs seem to perform better. the odyssey only has 220 cca acording to their website so imo it would suck in the winter months. that is half of what the braille 2015 has and i had that one. it didn't last. if you are living in winter climates the only one i would get is the braille 3121 which although weighs the same as stock it puts out much more power. braille also recommends this battery for engines that are boosted. here is what i have found
