Only used for 500 miles. This is the newer model with gasket material bonded to both sides of the spacer. The new cost for the basic plenum spacer (non-isothermal) is $265.

$200 shipped. Note that the plenum spacer posts are not included here. You'll need to talk to Motordyne and order new plenum spacer posts though (very minimal cost if any) as the ones I have can't be re-used.

As for isothermal parts, I will throw in a brand-new CCV (coolant control valve) kit for an extra $10. Comes with the valve, nozzles, clamps, etc. See my past posts if you need more info. I also have an extra aramid gasket too for another $10.

Heck, if you're around Houston I'll even install them for you.
