Show original supplier description
The Z1 Motorsports Plenum Spacer is an angled aluminum component specifically designed for the Nissan 350Z and Infiniti G35 models equipped with the VQ35DE engine. This spacer is installed between the upper and lower plenums to optimize airflow distribution, directing more air to the front cylinders. This enhancement results in a tangible increase in mid-range torque and top-end power, offering a significant performance boost for the money. It is constructed from aluminum and features a tapered design, with dimensions ranging from 7/16th to 3/8th of an inch (or 5/16''-1/2'' as stated in some evidence). The kit includes the plenum spacer, an OEM plenum gasket, and various mounting bolts and washers required for installation. Installation details and manuals are available, and customers have reported straightforward installations with noticeable performance improvements, especially when combined with other supporting modifications such as a Z1 tune or cold air intake. *** Please note: This item is not for sale or use in California. ***
