if you do a search on the forum, you'll find a lot of info. Basically, don't waste your money. If you want performance, CAI is alway better than Short Ram (which Weapon R is). but if you really want a Short Ram, stick with Injen - long (CAI) or short, it's among the best for our cars. Other good choices are K&N, and Comptech. I might be missing something, so use the search option above
