350z 03' - 05' Motordyne 5/16 Iso Thermal Plenum Spacer

The Motordyne Iso Thermal plenum spacer adds 12HP-14HP and reduces the effect of power robbing heat soak by thermally isolating both the upper and lower plenum. Its 5/16" thickness provides the best overall performance and 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.

I just installed this in my 2005 350Z and it makes the car feel stronger immediately! The installation for a beginner like myself only took about 1 hour. Great Instructions were included and the video online was very helpful. If you want your Z to get a quick HP gain get this product!
