Most times, you’ll see 15+ horsepower from adding a plenum spacer to your 350Z. It’s a weird problem to have, but all VQ35DE engines suffer from it.īy the time they introduced the VQ35HR, Nissan knew of the problem and fixed it with the new HR engine. By spacing the upper and lower parts of the plenum further apart, you increase the volume of the plenum which solves the air distribution problem. A plenum spacer is just a metal spacer with the shape of the plenum. On the 350Z, the plenum is split into two pieces: an upper and a lower. This airflow problem is where plenum spacers come into play. The culprit of the air distribution problem is the size and design of the intake plenum. On the VQ35DE (not HR) the intake manifold does not evenly distribute air to each cylinder. Unfortunately, the 350Z is not one of these vehicles. Most of the time, the manufacturer gets the design perfect, and other than mild polishing there is no benefit to modifying the intake manifold. Most vehicles use a one or two-piece intake manifold which makes the manufacturing process more straightforward and aid in assembly. To help you determine what modifications are best for you, we created this short list of the best bang-for-buck modifications for your Z.

Of course, there is a massive aftermarket for the 350Z and deciding what mods to install first can be a daunting task.
