Coolant Crossover Kit

99-04 Lightning & 02-03 Harley Davidson Lower Intake Manifold AKA "TURKEY-PAN"

Upgrade your engine's cooling efficiency with this Coolant Crossover Kit, engineered to equalize coolant flow between cylinder heads and eliminate hot spots that compromise performance. By establishing a direct cross-link, this mod ensures consistent temperatures across all cylinders—particularly critical for rear cylinders #7 & #8 prone to overheating which leads to detonation. The integrated design purges air pockets for simplified bleeding, while strategically positioned sensor ports enhance monitoring capabilities. Ideal for forced induction and high-performance builds, this kit prevents detonation and engine damage caused by uneven thermal distribution. Transform your V-engine cooling system and unlock reliable power.

Key Purposes:

• Even Coolant Distribution: Factory designs can leave the driver's side or rear cylinders with poor flow, creating hot spots. Crossover mods directly feed coolant to these areas.
• Air Pocket Removal: By connecting high points, these mods create a path for trapped air (steam pockets) to escape to the radiator/overflow, making system bleeding much easier and preventing pressure issues.
• Improved Tuning & Safety: Eliminating hot spots prevents detonation and allows for safer, more aggressive tuning, protecting the engine.
