Description 20v 4age – Intake adapter to an ITG combined filter This filter adapter plate is for those that have a quad throttle conversion and wish to use long velocity stacks with a method of filtration that’s reliable, low restriction and easy to work with. For most people the Pipercross adapters are a better solution (see related products) as they allow up to 100mm velocity stacks. However if space is at a premium the flat (not dome) type ITG 40 series filters may well be the best choice.   Suits – ITG40 series combined filters – Velocity stacks up to 70mm in length with the ITG40-100 (not the dome type). – Choice of a plate to suit silvertop or blacktop throttles – WILL NOT SUIT the spacing of throttles as used with our 3sge Beams manifolds. – WILL NOT SUIT most right hand drive – rear wheel drive vehicles due to clearance issues such as the location of the clutch master cylinder. The customer will need to check for adequate clearance.   Additional notes – Can be mounted upside down by flipping plate for more clearance if needed. – Plate material is either 304 stainless or aluminium. – Filters can be purchased though Merlin motorsports online store in the United Kingdom.
