The RUST Low Quality Spark Plugs are a vehicle component for any of the available modular vehicle engines. Facepunch added the modular vehicles in the Modular Vehicle Component Update on the 3rd of July, 2020.
Engine components, unlike modules themselves, may be added to a car in the field, or you can add them by having the vehicle raised on a powered Modular Car Lift.
All engines require a number of set components of assorted types for the vehicle to function.
Low quality parts such as the Low Quality Carburetor, Low Quality Crankshaft, Low Quality Pistons, Low Quality Spark Plugs, and Low Quality Valves are the baseline bottom of the barrel minimum required to make modular car engines function and perform quite poorly compared to the medium and high quality variations.
This component promotes the engine’s rate of acceleration but is the lowest quality available. Higher quality components perform much better in this regard.
Low quality engine components may be found in assorted car component boxes around the map or may be researched and crafted exclusively at the Tier 1 Workbench.
