Using our unique Two-Piece System the cool air from the intercooler is now insulated and kept cool by our high temperature composite intake material. The extremely hot air from the turbo now exits though a separate aluminum elbow. By separating the incredibly hot turbo-charged air elbow from the cooled air inside the intake manifold, CFM+ have negated the effect of transferring heat back into your cool air flow. Bench glow testing shows a significant increase in air flow through our unique two-piece system. This means better economy, more power, lower EGTs and faster turbo spool up. FREE Shipping!
