BLOX Racing Gen2 Hypertemp Plenum Spacer - 5/16in - 350Z-Hardware Kit Only

If you're looking to get a little more out of your 350Z's engine, a plenum spacer can help. This 5/16-inch spacer from BLOX Racing is designed to increase the volume of your intake manifold, which can lead to improved throttle response and a slight bump in horsepower. It works by creating more space for the air-fuel mixture to gather before entering the cylinders.

This particular kit is the hardware-only version, meaning it includes all the necessary bolts, nuts, and gaskets you'll need to install the spacer. The spacer itself is made from a material that helps reduce heat transfer from the engine to the intake manifold, keeping the incoming air cooler and denser. Cooler air means more oxygen for combustion, which is key to making more power. It's a well-built piece that fits right into the factory setup.
