@oohyeah Benefits are twofold. First the cp-e bar and plate design keeps the boosted air temps lower than the oem unit so you can run more timing and therefore get more hp before temps detonate the fuel/air mix. Second the cp-e has less restriction so you only lose about 2psi between the turbo and the intake manifold. With the oem unit you lose about 6psi. When the turbo doesn't have to work as hard the air charge is cooler and you make more power. Not to mention when the turbo doesn't work as hard it lasts longer.
