The Final Word
For several days following the install, we had plenty of seat time in the Frontier to gauge the effects of the new intake, and we can honestly say that there is a very noticeable difference. When the throttle is punched, especially while cruising the freeway, the added power can easily be felt, especially in the truck's sweet spot. The sound of additional air being sucked into the intake is mellow enough not to be annoying on long drives. During dyno testing of Stillen's Hi-Flow intake kit, we measured a gain of 11.2hp (see accompanying chart), which is substantial for any stand-alone intake system.
