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!
