I have been doing some additional reading on the plenum riser, they make the comment that it can reduce the low end torque and give the additional power above 3000 rpm, did your finding show this, also they talk about a 5/16 and a 1/2 spacer, with the biggest increase using the 1/2 inch, have you done any testing with these thicknesses.
As for the aluminum spacer is the Pathfinder less prone to thermal transfer because the plenum is plastic, would a composite be better?
You show a gasket with the kit or 2 , these are not like the ones on the Nissan engine breakdown section, is this a standard gasket or one you have produced.
