4AGE 20v ITB

Weldspeed 4AGE Intake Manifolds are designed in consultation with the world's leading 4AGE engine specialists & guided by the latest in engine intake research combined with a no compromise approach in metallurgy and production methods.

These intakes are engineered for high boost levels and high engine speeds from the get-go! All Weldspeed intake manifold runner bases are precision CNC machined from 6061-T6 billet aluminium with integrated bell mouths.

Expertly TIG welded with a v-groove design typical with pressure vessel standards. The CFD designed plenum is shaped to deliver air mass evenly to all four cylinders whilst short runner lengths help high revving engines continue to breathe well over 8000rpm. The orientation of the plenum can be ordered to front-of-engine or rear-of-engine facing and utilises Viton O-ring flange seals.

All manifolds are supplied in our Satin finish.
