GDI requires high-pressure injectors to inject gasoline  directly into the cylinder rather than the intake port. In so doing, GDI improves fuel atomization, promotes cleaner burn, boosts fuel efficiency—and more importantly for the racing brain—improves performance.

Twenty-four years ago, a similar transformation took place in head gasket design when the term MLS entered our speech. The revolutionary multi-layer steel gaskets featured three or four layers of thin stainless steel sheets. Spring loaded, the top and bottom layers of the MLS gasket push against the center core to combat high combustion pressures.
