Splash oil will not be an issue with a carbon fiber valley shield, but I am testing the stock intake setup too. I don't see splash oil having very much of an affect on the intake temps since it already has a big metal shield covering the whole bottom.

I bet it will make a measurable difference on my SuperVic, but we'll see what it does on a stock intake.

Also, if you're going to space out your intake, watch the gap at the front and back between the intake and lifter valley. You could end up raising the intake up too much to seal with RTV.
The material I ordered is actually .003 thinner then a stock replacement FelPro intake gasket .
