    Nice Upgrade

    These underdrive pulleys are a quick and easy way to free up some horsepower without spending too much money. Bolted them up in about half an hour and felt an immediate performance gain- I'd guess 10 or 15 horsepower. The engine seems to rev up a bit quicker as well. A word of advice, make sure your cooling system and charging system are in tip top shape before installing these. Underdrive pulleys will reveal weaknesses in either of those areas, but no, they will NOT cause your car to overheat or the battery to not charge as some say- so long as the those systems are working properly.

    thanks bbk your awesome product worked for about 10 miles of driving till it killed my alternator and i had to buy a new one. Beware of it. Easy install minus the fan blade hole not fitting properly its just off being a bit too small. It added a little noticeable horse. loved them till the problems started looks good too. Overall buy them at your own risk.
