Q-Shield is a patented technology that significantly reduces the consumption of diesel fuel or gasoline in internal combustion engines. Q-Shield™ technology employs space-age Thermal Insulators to key parts of the engine. It does not invade any engine components. Q-Shield™ is fitted to the total air intake system: compressor, turbocharger, exhaust manifold, and intercooler. This total shielding produces a more complete combustion rate. Q-Shield™ operates in engine types with or without intercoolers. Q-Shield™ is available through Norman G. Clark.
