1.4L/1.6L Vauxhall Inlet Manifold for 7-deg Mounted Engines
1.4L/1.6L Vauxhall Inlet manifold for 7-degree mounted engines. This inlet manifold is normally used when the engine is installed into an original car such as Corsa or Astra, the engine is tilted towards the exhaust by 7-degrees, therefore when this manifold is used it means that if carburettors are used they would be parallel to the ground and therefore the float chambers will work correctly.
The 1.4L/1.6L Vauxhall inlet manifolds are designed to allow the carburettors/twin or MT type throttle bodies to sit parallel to the ground, the choice is dependant on whether your engine has been mounted vertically or at 7-degrees. Due to the variations in port shape on the small block 16v engines, the inlet manifold port shape as it meets the head is made to the smallest size, this way the user can modify it to suit the various port shapes available.
