Be careful. If you put them on backwards you'll actually LOSE horsepower. Otherwise a quality mod

 

actually.... im thinking of putting 2 sets on.... one frontwards one backwards... i figure by putting them back to back like this, i'll actually increase my aerodynamics and should be able to reach 170mph.....

i agree... this is soooo sadddd
