ProTek RC 3.5" 1/8 Exhaust Manifold Spring (2) (Long) - PTK-7100

🏁 ProTek R/C Long Exhaust Manifold Springs (89mm)

High-Temperature, High-Durability Manifold Springs

This is a set of two ProTek R/C Long Exhaust Manifold Springs, designed specifically for 1/8 scale nitro engines. These springs secure the tuned pipe manifold to the engine’s exhaust port—a critical connection that must withstand extreme vibration and intense engine heat.

Over time, manifold springs naturally lose tension due to constant heat cycles and engine vibration. When weakened, they can break, leading to leaks, blown manifold gaskets, or even serious engine damage. Replacing worn springs with high-quality ProTek units ensures a tight, reliable seal for optimal performance and durability.

• Designed for 1/8 scale nitro engines
