...your OE airbox for noise reduction, then here is the cure .

Obviously the standard airbox is only 65mm intake, which is too small for the 76mm hose required for the T4. However, the entry into the Escort airbox is actually 87mm, but features a glued in plastic reducer.



This can be cut off and removed, leaving the full 87mm entry hole.



We then do a billet alloy machined intake adapter that pushes in to this and sleeves down to the correct 76mm for the T4.









This does actually push in fully, but it is a bitch to get out, so I didn’t push it fully home .

We also do one that allows the fitting of a GT30 / GT35 (100mm) hose to the standard airbox – obviously the entry is reduced to 85mm where it goes into airbox, but it allows the fitting of a proper 100mm hose whilst retaining the OE look and sound reduction .

 

looks job done too me

 

 

Combined with this, is a complete cure for all your T4 on an Escort Cosworth issues
