The EGR stands for Exhaust Gas Recirculation. It routes the exhaust gases back into your intake manifold in order for a more thorough burning in order to reduce emissions.

Eliminating the EGR system will prevent those hot and dirty exhaust gases from entering your intake manifold, resulting in more oxygen making it into your combustion chamber for more HP. The HP gains should only be 1-2 hp, but your intake manifold will remain cleaner for longer since carbon buildup from the exhaust gases won’t be an issue.

But the EGR Block Plate Kit we currently sell is intended for those that have done an engine swap with the 04-06 Maxima or 05-06 Altima VQ35DE engine and are using a non-EGR ECM such as the 95-99 or 02-03 Maxima ECM. Or you may need this kit if you would like to purchase a used spare 6th gen (04-06) Maxima UIM, but don't need to run an EGR system.

At this time, this kit is not intended to eliminate the EGR system on a street driven 04-06 Maxima or 05-06 Altima, since that will decreases your chances of passing emissions as well as give you a check engine light. So no EGR block plug will be included for the RH exhaust manifold. But we are actively testing this right now on some late model EGR Maximas and Altimas to see if we can reliably eliminate the EGR system on a street driven car without any codes popping up.

The original post has been edited to include this extra information.

Here is an illustration that explains what I am referring to when I say that various aspects from each of the two mating manifolds are used. This illustration shows what is involved in designing only the Elbow Spacer used in our 02-08 Maxima Spacer Kit. There are two manifolds used to make this unique Spacer design, the Upper Intake Manifold (UIM) and the Elbow. If only one intake manifold was copied, it wouldn't result in the beautiful Elbow Spacer design you see at the bottom of the picture. This design technique was also used in our Upper Intake Manifold Spacer with the same kit. If we simply copied only one manifold, our Spacers would not look anything like what they do.
