MGB Carburetor Heat Shield Insulation

These insulation pads are intended to protect the carburetor float bowls from engine and exhaust heat and prevent vapor lock. If your insulation is original, it is likely deteriorated and may contain asbestos. Entire heat shield replacements are available with new insulation already installed but can cost nearly $70. Purchasing an entirely new heat shield is often not necessary because the original heat shield can usually be cleaned up, repaired, and powder coated or painted for the high-temperature environment.

These pre-cut replacements are very close to the originals and provide a finishing touch to your restored heat shield and carburetor rebuild. The ceramic fiber material can withstand up to 2300 degrees F, is 1/8 inch thick like the original material, and is rated for outdoor use.

$15.00 + $2.60 S&H to lower 48 states

Included with the HS4 heat shield insulation pads are 10 brass rivets similar to original (3/16 inch diameter, 3/8 inch diameter head). The metal heat shield is not included but is shown in black high-temperature powder coat in the image above as an example. These insulation pads are based off of the original ones found on a 1967 MGB roadster but should fit any MGB SU HS4 carburetor setup. Please verify that these insulation pads are correct for your vehicle by referring to the dimensioned drawing below. If these insulation pads are not correct for your application, please email me and I may be able to accommodate your custom needs.

The HIF4 insulation pads are installed simply by bending over the tabs incorporated into the metal heat shield. The metal heat shield is not included but is shown in the images above as an example. While the insulation pads should fit any MGB SU HIF4 carburetor setup, please verify that they are correct for your vehicle by referring to the dimensioned drawing below. If these insulation pads are not correct for your application, please email me and I may be able to accommodate your custom needs.
