FX Royal Racing Engines Small Radius Long Off-road Manifold.

For Maximum performance and reliability use only original FX manifolds.

There are different types of FX manifolds, each designed for particular track conditions and for particular engines. These recommended manifolds will help optimize performance for the majority of track conditions. However for some specific track conditions or for some fine tuning of the engine settings, you may want to change the manifold as desired.

Manifold recommendations:

• Short Manifold: Recommended for tracks with long main straights to achieve the highest RPM, but with reduced bottom-end performance in the low RPM range.
• Medium Manifold: Recommended for medium (or “standard”) sized tracks.
• Long Manifold: Recommended for short tracks where bottom-end, lower-RPM performance is required.
