it ranks #2 for worse thing i ever bought for my car besides used tires.

it ranks #3 for most useless thing ive ever bought for my car besides a cinnamon air freshner and a honda alarm system.

i got a set of unorthodox pulleys and they are great, but the only problem i have is the alternator it underdrives too much. keep the stock alternator pulley. the rest are great.
