Second gen 3.5 5/16 Copper Iso Thermal Intake Spacer

[Brewcity1]

Hello all,

Does anyone know if the second generation 3.5 engine is the same as the first generation?
I have the 3.5 (obviously with the FX35 badge), and have read about the nice affects of the Motordyne 5/16 Copper Iso Thermal Intake Spacer.

However, they are only available for the first generation 3.5L engines.
Will those spacers work on the 2nd gen engines...or are they different?

Thanks for the help!
