Do you guys havea 25mm manifold insulator for the LLT engine on your website?What procedure must be fwollowed to ensurereasonable clearance under the bonnet?

That specific insulator is only for a Camaro as they have much more bonnet clearance Lots of cutting is required. The only manifold insulator that will fit an LLT V6 in a VE is 6.35mm thick, as shown in the link below. However we do have a manifold insulator that will fit a LLT SIDI VE. However this product comprises of a 2 X 6.35mm thick manifold insulator. http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectPath=/Shops/mace/Products/MI621
