Ported Intake Manifold Evo 4-8

Description

Introducing our ported intake manifold for Evo's 4-8

All manifolds are degreased and cleaned down prior to any work being carried out.

We then carry out the below modifications -

• We start by cutting the plenum open to give us access to the inside of the manifold 

• Port and flow the plenum. The plenum is then smoothed and transitioned all the way through

• Modify and smooth out the runner entries

• Runners are then port matched perfectly to the OEM gasket 

• Add material to the underside of the throttle body flange so that we can then remove the very sharp transition on the inside and replace it with a very smooth radius on the throttle body inlet (This helps with airflow into cylinder 4 which is a weak point on these engines and the most prone to detonation)

• Throttle body flange can be left as the original size or can be enlarged to 65mm

• Weld the plenum back on

• Tidy up any welds on the inside of the plenum

• Vapour blast both the inside and outside

Additional options are also available - 

• Throttle body inlet modified to suit a Bosch DBW throttle body

• Remove any unwanted vacuum ports

• Additional vacuum ports

• Air intake temp sensor flange welded on

• Powder coating
