APS Cast Upper Intake Plenum - 2003-2006 Nissan 350z

At high engine horsepower levels the stock inlet plenum on the 2003-2006 Nissan 350z not only becomes restrictive, but more importantly the air distribution across cylinders becomes uneven and results in a variation in air/fuel mixtures from cylinder to cylinder.

To solve these issues, APS has developed what is arguably the ultimate inlet plenum for the 2003-2006 Nissan 350Z in high horsepower naturally aspirated and forced induction applications.

In day to day driving conditions, the APS Tall Boy plenum delivers crisp throttle response and higher torque - resulting in an even more enjoyable drive. And the higher the horsepower, the wilder the ride!

Cast in light weight alloy and then NC precision machined, the APS plenum pumps-up the internal plenum volume and delivers the optimum distribution of air to each inlet trumpet.
