good choice

 

does swapping out the pully really do anything...... my buddy was like"man, theyre just for show" and im like "no, they actually relieve some of the stress on ur engine" correct me if im wrong

 

i dont see how its for show cuz its nothing special looks wise. if you use the ac, you'll notice a difference as the pulley directs power from the accessories to the engine. Also, the pulley is alot lighter and smaller diameter, which will spin quicker giving your car a more peppy response
