The VQ Boys Performance ported lower collector manifold is one of the best ways to increase your VQ's power. This part will work on both VQ35DE and Rev-Up engines. For ANY VQ35DE build, this is a critical piece to making more horsepower! For VQ35DE engines (Non Rev-Up), adding the ported lower collector to the Non Rev-Up VQ35DE engine will result in a steady increase of linear power from low-to-high range rpm.
Gains have been confirmed between 4-8 hp, depending on other mods on the vehicle. For Rev-Up engines, adding this lower collector will result in power gains up to 12-18 HP and 10-18 lbs/ft torque, depending on what other supporting mods you have installed.
