Throttle Body Gasket Kit - 70mm Ford 4.6L

The Throttle Body Gasket Kit – 70mm Ford 4.6L (BBK Performance Model 1585) is an OEM-quality replacement gasket designed for Ford's modular engine platform across 1996–2004 vehicles. This component seals the critical junction between the throttle body and intake manifold, preventing vacuum leaks that degrade idle quality, fuel economy, and engine response. Whether you're diagnosing a rough idle, performing routine maintenance, or rebuilding your fuel induction system, a fresh gasket kit is essential to restore a tight, leak-free seal.

This kit features a 70mm composite gasket engineered to withstand the thermal cycling and pressure cycles inherent to the Ford 4.6L modular engine. The composite construction—offering superior durability compared to paper gaskets—resists fuel vapors, coolant exposure, and engine heat without warping or compressing over time. The gasket's precision fit ensures proper seating on both the throttle body flange and manifold surface, eliminating the micro-leaks that occur with worn or reused gaskets. Installation is straightforward for DIY mechanics and professional technicians alike, requiring only basic hand tools and attention to proper torque specifications.

This gasket kit is ideal for Ford car and truck owners maintaining or modifying 4.6L engines, particularly those upgrading intake manifolds, throttle bodies, or addressing vacuum-related driveability issues. Compatible with Ford Mustang, F-Series trucks, and other modular-engine platforms from the 1996–2004 era, it's a cost-effective preventive maintenance item that prevents costly air-fuel mixture imbalances. Keep this kit on hand before disassembly to avoid extended downtime and ensure optimal engine performance upon reassembly.
