New Intake Manifold option

[Maddmatts]

I just noticed on www.rockauto.com that Dorman offers a new intake manifold (P/N 615-380) that's noticeably different from the original.

Compared to the OE manifold, it has almost no structural ribs and the vacuum bottle is less cylindrical. It still has the tumblers in the runners so performance will likely be the same.

My biggest hope is that it finally offers a better, internal PCV valve.

Looks like it's been discussed on cruzetalk a year ago and uses the exact same type of valve. Dorman actually added a post there stating that the valve is held in place more securely on the opposite side of the nub we typically look at to keep it from being sucked out.

for the price.. i just did the intake mod, for longevity and ease of maint. but i wasn't expecting to sell it but , them ridiculous high offers with cash in hand... hard to refuse.

Yeah the Dorman model offers no benefits other than being cheaper than the dealer ones.
