it depends on the engine, but for the most part a spacer is junk. on the 4.7 it is worthless.

there is a thread on here about backflushing the heater core. try that first before you go replacing parts.

superchips 3715 is around 300 and a good investment, although it will be more noticible after some more mods are done first.
