Just wanted to know how hard it is to install one on my year and make? Can my Mechanic friend do it or should i just take it to the shop? Also is the other complementary pully worth getting? ( the one for the air and stuff)
Thanks again guys !!

I just put mine on and it aint that hard the hardest part was getting the belt back on.Plus i also put the alternator pulley on if you got an impact gun and 45 minutes it can be done. definitely revs much quicker now ,but i still didnt get rid of the shake i got at an idle any ideas good luck if you attempt it .
