These things are awesome; simply remove your oem pulley, and install this in place. This lightweight, more aggressive pulley will get you an extra 8-10mph. BONUS! Plus, you keep your oem reliability. Keep in mind, this will hurt acceleration from a dead stop and low speed. With the spree, you can't have it both ways. This little dude will get you cruising right along for under $60.
