Skunk2's revised composite plenum spacer for Nissan/Infiniti VQ35 engines (350Z/G35) increases plenum volume and lowers intake temperatures to improve throttle response and fuel efficiency. The 5/8-inch composite spacer offers superior thermal insulation over aluminum, is perimeter-sealed to eliminate the OEM gasket, and includes hardware and water-line bypass components for an easy install that can yield measurable horsepower and efficiency gains.
