Atomic Intake Plenum Gasket – Suit Ford AU, BA, BF 4.0L 6cyl
No leaks. No heat soak. No compromise.
Tired of vacuum leaks, heat soak, or warped flanges on your intake? The Atomic Intake Plenum Gasket is the solution. Designed for Ford AU, BA, and BF 4.0L SOHC and DOHC engines, this high-performance gasket delivers a precise seal and acts as a thermal barrier between the head and plenum to reduce intake air temps.
Made from a thick composite material, it spaces the plenum off the head to help reduce heat transfer—keeping intake temps lower and performance more consistent. Whether you're reassembling a stock setup or bolting on a performance plenum, this is the gasket to trust.
Why It Works:
• Suits Ford AU, BA, BF 4.0L SOHC & DOHC engines
• Thicker composite design insulates intake from head
• Reduces heat soak for more stable intake temps
• Prevents vacuum leaks, idle issues, and flange warping
• High-temp, fuel-resistant material – built to last
• Precision-cut for perfect OEM fit
• Used in all Atomic-built engines
