Today I installed my 5/16 copper iso thermal plenum spacer from Motordyne. It was fairly straight forward install, but I would strongly suggest having someone assist in the install. It took me about two and a half hours considering it was just me in a poorly lit garage. I did the ECU reset with the negative battery cable disconnected then pumping the brake. I'm unsure if I needed to, but since the battery cable was disconnected for the install why not. The biggest help was Eugene Turkov's DIY video on infinitihelp.com. Everything fit perfect and she cranked up without any problems. Smooth Idle and no CEL. Took it for a run around town and immediately noticed the difference. A lil more get up and go for not alot of $. Got home popped the hood and the plenum wasn' t even warm to the touch after an hour of driving. All in all very pleased with Tony and his product. Thanks

^ I remember it well.... great mod for minimizing heat soak.

Right on Fenton78! Glad to hear your results.

That is my next mod.
I'm sure that I need someones help...
Congratulation!!!

Go to the Motordyne web site and Tony's cell # is listed, he will be more than willing to assist in any way as I found out. Good people to deal with @ Motordyne. Also check out infinitihelp.com there is DIY video that helped me alot.

Agreed. Big thumbs up for a great product.
