The resonator is that big plastic box on the top of your engine that says "Duramax." This plug allows you to remove that and plug the orifice that the box attaches to. Now, onto the second part, why you need it. For starters, the resonator box is big and bulky, and you simply don't need it. Its intention is to quiet down the incoming air noise, but it also creates considerable air turbulence before air enters into the engine. Thus, by eliminating it, you will gain a small amount of air intake sound (which we tend to like) and some turbo responsiveness due to the increase in linear, tabulated airflow.

Built from machined aluminum, this is no cheap piece of plastic. The neck of the plug is also machined to accept the included o-ring to ensure a leak free seal.

IMPORTANT NOTE:
GRP's product line was originally intended for installation shops and to be purchased in bulk quantity, which in turn means that there are no installation instructions that come with any of their products. We feel that this compromise is easily countered with the exceptional craftsmanship that goes into these kits, as well as the price point. If you are unsure of how to install any of their components, but still want to tackle the job yourself, there are plenty of generic installation videos available online that will allow you to still take advantage of the benefits of purchasing GRP.
