Description
This heat shield is very important to keep the hot air from your exhaust manifold away from your HS4 carburettors. With age the heat resitant material will fall part and will not be able to do its job. Replace you old or lost heat shield to keep your MGB running its best. Note this will only be correct for the 1962 to 1971 MGB with HS4 carburettors which is the stock carburettors for this year range of MGB. Cross Reference 451-005
