We?ve all heard the saying “Bigger is Better”?.that statement couldn?t be more true when it comes to turbocharged cars and intake manifolds. Introducing our aluminum DRAG VERSION sheetmetal intake manifold for the 4G63 DSM. This intake manifold is for the hard core racers only! If your running a 35R or larger turbo, continue reading??if your not then now is a good time to hit the browsers BACK button!
These are hand made, TIG welded from high quality 6061 T6 aluminum. The flanges are all CNC machined and surfaced for precise fitment and a leak free seal. The plenum measures in approx. at a whopping 5 liters. Velocity stacks are CNC machined into each plenum bottom to improve airflow by 10-15%. The vacuum ports are placed on the underside of the plenum for a clean professional look. They are available unpolished or with a mirror like polish. Included are 4 new 8mmx1.25mm 70mm bolts for the stock throttle body. Expected gains can be anywhere from 10-45 HP depending upon your setup!
These manifolds are designed for DSM’s with eliminated EGR. Some modifications to your coil pack mounts, and upper intercooler pipes may be needed as this manifold sits down a lot lower then stock. If using the Accufab and other aftermarket throttle bodies please note that the throttle cable and TPS sensors may need modifying.
