defintely for for the 5/16 thermal spacers and if possible with the combination of the mrev2 for 05+ rev up engines and higher for the best gains.
i believe for the engines that are not rev up..you have the option of the spacers or the mrev..unless you have additional mods that would support both of them at the same time
