Republished from DieselWorldMag.com – All engines, diesels included, are essentially giant air pumps when you think of them in their most basic form. The pistons move up and down in a cylinder, drawing in and pushing out air and combusted fuel to make power. The gatekeeper becomes the cylinder head and intake and exhaust valves.
ODON, Indiana – The new Wagler S-series (Street) & X-series (Extreme) cylinder heads for GM Duramax diesels are now available directly from Wagler Competition Products. The new custom-built high performance heads are the first of its kind in the diesel aftermarket world, according to Jeremy Wagler, president and CEO of Wagler Competition.
