    Adult Content 1.9 cdti airbox..! de-restrict?

    i have just fitted a 1.9cdti airbox to my GSI after having a derestricted (drilled) standard zlet airbox and it feels.. less responsive and the dump valve (baileys) is quieter

    Question is should i de-restrict the 1.9 airbox? how have people done this? dont really want to go butchering and drilling if there are otherways..


    thanks in advance for all help given

    dont drill it, de restricting it is about removing the cone that blocks half the filter. Improve the cold air feed and fit a panel filter. Drilling lets hot air in from the engine bay. It will be noisy but less powerfull.
