Give your Savage a boost with the Nitro Star F3.5 engine! This .21 cubic inch engine is 3.5cc of pure, massive muscle!

With 2.5hp on tap, the rear-exhaust Nitro Star F3.5 is supremely powerful and is a great match for any car or truck that can take big-block engines.

The large heatsink is anodized a cool black to enhance the heat dissipation properties of the CNC-machined billet heat. The aluminium case also features loads of cooling fins to release heat, letting the engine keep its cool under any circumstances!

Protecting the internal parts of the engine is a large oiled foam air filter, which is included with the engine. A huge composite-body slide-type carburettor enables the fuel to reach the combustion chamber without boiling away, and features all the adjustments you need to keep the engine tuned for all conditions.

Inside, the Nitro Star F3.5 features industry-standard ABC construction for longevity and ease of use.

To get the engine going, the Nitro Star F3.5 is equipped with a tough pullstarter as standard. This can be replaced with an #HP87130 HPI Roto Start system for push-button starting!

Includes air filter. Make sure to break in engine properly, according to the instructions included.
