    I'm changing left and right pcv hoses that run from the plenum. The 89 n/a hoses are unrestricted, however the replacement ones are. Will this be an issue? Thanks.

    I don't believe any of them were factory fitted without the restrictors, but regardless running hoses with the restrictors is fine and won't cause you any troubles.

    They would have had restrictors from the factory. The restrictors may have been removed in conjunction with a PCV delete.

    Curious to what your thoughts are on pcv delete Rob?

    Standard operating procedure for me. As well as removing the restrictors from the front hoses.

    I'm sure there are people who disagree, and that's fine, but anecdotally speaking there don't seem to be any adverse effects.

    Good to hear. The 2 front hoses, do you run straight to the accordian pipes ? or breathers / catch can

    I ran mine to a catch can. Was suprised by what was caught. After about 6 laps this is what I caught. That is a tiny 300ml can, there was about 90ml in there.
