Spark Plug Tube Seals - Late Hemi

The Milodon Spark Plug Tube Seals - Late Hemi are essential components for high-performance Mopar 426 Hemi engine builds. These seals are designed to prevent oil from entering the spark plug tubes, addressing a common issue in Hemi engines where the spark plugs are positioned deep within the cylinder heads. By ensuring a clean and dry environment for ignition components, these seals help maintain consistent spark delivery and prevent fouling during high-stress operation.

These seals utilize an O-ring design that provides effective sealing capabilities, ensuring that oil remains contained within the valve train area. The construction is designed to withstand the extreme heat cycles generated by the 426 Hemi engine, maintaining performance without warping or degrading. This set of eight seals is precision-engineered to fit the specific geometry of late-model Hemi heads, ensuring a proper fit against the tube and the valve cover.

Engineered specifically for the Mopar 426 Hemi, the Milodon Spark Plug Tube Seals - Late Hemi are a direct-fit upgrade for any professional engine assembly or routine maintenance project. They are particularly beneficial for restorers and performance enthusiasts aiming to maintain the integrity of their legendary Mopar powerplants. Whether building a drag strip competitor or a performance street machine, these seals are a vital component for optimal engine function.
