    Hello all,

    Does anyone know the I.D of the pipes in the engine bay, i.e one that connect to top of throttle body area, and one that goes into the top of coolant bottle.

    I wanna replace mine with Black Silicone as im doing a tidy up of my whole engine bay.

    Thanks

    Don't use vacuum pipe for water though... you will need the fabric reinforced stuff similar to boost hoses...
