BAR-TEK® TIP!
We recommend to fill up with 102 octane fuel. This will give your engine more power because it knocks less! The turbocharger should not be too old and the engine should be in good condition. The basis must be right. Check the red pressure hose on the turbocharger; it's often leaking because it can't stand the heat from the manifold. Our Forge silicone hose can help!
