        I have an aftermarket bov for my own reasons, but I know the plastic oem is fine...
        Lol good luck with that!!
        They generally have a measurable leak from around 15psi.

          yup def a leak. Faux watch the boost solenoid duty cycle increase to compensate for leakage on an oem valve. Pid controller bumps up 5 to 10% on the adaptronic to compensate. Just not as noticeable with speed density

            Crap...

            There is no way that plastic that thin with the flow rate required will hold off 100psi & I don't give a shit how you design it.
            Otherwise there would be no OEM alloy units 'cause they'd all use cheaper plastic jobbies.

            Think about it for a bit: Globally a 1,000,000 cars made by Mitsubishi that need a BOV. By using plastic BOVs Mitsubishi (very conservatively) save $5 per car because a plastic BOV will apparently handle up to 100psi at any temperature.... But no, they fit metal ones.
            How much does that add up to when compared to the cost of a global recall to replace faulty plastic BOVs with metal ones?

            But what would I know? I'm no expert, but I have spent a reasonable amount of time studying logistics, material strengths and fluid dynamics as a career... but I'm sure there'll still be shit flying around.
            Maybe I shouldn't post after a bottle of nice red, but fuck me...
