Just out of curiosity whats the benefits of the ducted sump guard? Is it just to dissipate heat from the turbo?
I had my manifold and turbo exhaust housing black ceramic coated as I removed the factory heat shield when i fitted the latter style R manifold to try and elevate the heat it seems to work well.
I want to re fit the factory heat shield when i Fit the Japanifold i have if I ever pull my finger out.
