Skunk2 Pro Series 03-05 Nissan 350Z/Infiniti G35 5/8 in. Intake Plenum Spacer

Starting with a 5/8 inch thickness, this Skunk2 Pro Series intake plenum spacer is designed to increase the volume of your engine's intake plenum. This change helps to lower intake air temperatures, which can make a notable difference in how efficiently your engine breathes, especially for the front cylinders. It's a well-built component that fits a range of vehicles, including the Nissan 350Z, Infiniti G35, and Nissan Altima, among others from the 2003-2005 model years.

Unlike spacers made from aluminum, this one is constructed from an aerospace thermo-polymer composite. This material offers better thermal insulation, meaning it won't transfer as much heat from the engine to the intake air. Skunk2 also uses an injected seal around the perimeter, which creates a tight fit and eliminates the need for the factory gasket. The kit comes with all the necessary hardware, including parts to bypass the throttle body's water lines, making installation more straightforward. Just be aware that if you have the factory strut tower bar, you might need additional spacers to ensure clearance after installing this plenum spacer.
