cosx4

Cosworth mounts - carburettor to manifold

Developed by British-based racing engineers Cosworth, these buffers are specifically designed to be used in conjuction with Misab-plates.

The mounts are strong enough to ensure an airtight seal while also providing enough vibration damping.

Each mount consists of two cups and one rubber buffer.

Install the Misab-plates, install your carb(s), install the Cosworth mounts using a Nyloc nut (NOT included!) and set the distance between the cups to 2 millimeter, using a normal feeler gauge.

These mounts are supplied in sets of 4 complete mounts (as depicted) which is enough for one carburettor like a Dellorto DHLA or Weber DCOE.
