Motordyne Nissan 350Z 1/2″ Iso Thermal Plenum Spacer

The Motordyne Iso Thermal plenum spacer adds 12HP-14HP. It can reduce the heat transfer and heat soak by thermally isolating both the upper and lower plenum. 1/2″ thickness provides the best overall performance without compromises. This kit is fully compatible with your engine cover and strut bar. All Motordyne Iso Thermal systems keep your upper and lower plenum cooler without the risk of throttle body freezing when driving in cold weather. Each kit comes with everything you need for a complete installation.
