The MPG Plus wire line, including the GMS34-1923MPG, applies the same 0 ohm core technology found in the company's racing products to daily-driven applications like the Mercedes-Benz 190E, giving owners a factory-style fit with meaningfully better electrical conductivity than aging OEM wires.\u003c\/p\u003e\n\n\u003ch4\u003eFAQ\u003c\/h4\u003e\n\u003cstrong\u003eWhat is the GMS34-1923MPG?\u003c\/strong\u003e\n\u003cp\u003eThe GMS34-1923MPG is a Granatelli Motor Sports MPG Plus ignition wire set built specifically for the 1986-1993 Mercedes-Benz 190E 2.3L four-cylinder engine.
