The best bang for my buck (on my 2.7) was the Borla cat-back. Tried the Downey open element intake, but I felt that the underhood hot air was negating any increased air flow. So I put the stock air box back on and did the "fender elbow removal" mod. Truck runs good.

I also looked into the blower, but decided not to get into that for my daily driver.
