CNC Cut from a phenolic resin material the PREracing heatshield intake manifold spacers are an excellent addition to any engine build. While installation is very time consuming the resulting cooler inlet temperatures and reduced manifold heat soak are well worth the time. Performing a hard turbo inlet install, TGV delete, engine build, etc.. add these gaskets in place of lower manifold gaskets. RalliTEK recommends using a thin layer of high-temperature silicon to seal these gaskets to the manifold and head.
