I spend close to $300 only since I wanted to ensure correct fitment rather than making an intake myself for a fraction of the cost. however, when I took out the old air-intake box assembly, I realized the poor fitment. I had to professionally get the heat-metal shield cut to proper size, in addition, the hose adaptor for where the intake sensor goes was so poorly designed that it, in fact damaged the sensor! the adaptor was incorrectly shaped and did not fit. WORST PURCHASE!!
