Weiand Hi-Ram & Tunnel Ram Intake Manifold Replacement Gaskets

Weiand Hi-Ram and Tunnel Ram replacement intake manifold gaskets are purpose-built sealing solutions designed exclusively for Weiand's two-piece Hi-Ram and Tunnel Ram manifold systems. The unique two-piece architecture of these manifolds — featuring a separate upper top plate and lower runner section — requires a dedicated, application-matched gasket that generic off-the-shelf options cannot reliably replicate. Using the correct replacement gasket is critical to eliminating vacuum leaks and preserving the precise air/fuel ratios that high-performance applications demand.

Key Features:

• Direct-Fit Replacement Design: Engineered as true drop-in replacements for Weiand Hi-Ram and Tunnel Ram manifold assemblies, ensuring correct port alignment and a leak-free seal at the upper-to-lower manifold junction
• Factory-Spec Materials: Cut to factory specifications from high-quality gasket materials, these seals accommodate real-world mating surfaces and withstand the heat and pressure cycling common in high-performance and competition engines
• Vacuum Leak Prevention: Precision construction maintains a consistent, airtight seal between the upper and lower manifold sections, protecting air/fuel ratios and preserving maximum power output
• Competition-Ready Performance: Built for the demanding conditions found in drag racing, tractor and truck pulls, and performance marine applications — the same environments where Hi-Ram and Tunnel Ram manifold systems have proven themselves for decades
• Multiple Configurations Available: Offered across a range of manifold assembly part numbers and engine families — always select the gasket set that corresponds to your specific Weiand manifold assembly

About Weiand Hi-Ram Technology

Weiand has been at the forefront of performance induction since the 1930s. In 1968, Weiand introduced the iconic Hi-Ram manifold featuring its patented D-port runner technology, which delivers optimum air/fuel mixture velocity to the cylinder head intake ports for maximum naturally aspirated competition power. These replacement gaskets are the correct sealing solution to keep that legendary system performing at its best.
