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.



– 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.
