Replacement Manifold Spring for RC Tuners

When carrying out tune-ups, even small parts can change how an engine behaves. The Kyosho 39514-1 manifold spring helps secure manifold joints and preserves the exhaust seal for steadier running and fewer surprises on the track.

Function and Benefits

Made specifically for RC manifold assemblies, the Kyosho 39514-1 spring prevents unwanted movement and keeps the joint sealed. That stability supports consistent engine characteristics and reduces the chance of exhaust leaks affecting performance.

Fitting Notes

The spring fits a range of models and is quick to fit with normal hobby tools, so you can replace it at the bench or track without complicated disassembly.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this spring fit older Kyosho manifolds?

Many older Kyosho models using the same manifold layout accept the Kyosho 39514-1, but it is recommended to check the spring dimensions against your manifold before ordering.

Do I need to remove the engine to replace it?

In most cases you can access and swap the spring without dropping the engine by working at the manifold clamp area with pliers.

Can I reuse the old spring?

Reuse is possible if the spring still holds its shape and tension, but fitting a new Kyosho 39514-1 guarantees the intended clamp force.

Should I use grease on the manifold seal?

Only use a light assembly grease if your engine manual suggests it; avoid excess lubricant that might allow the joint to slip.
