pods filters are alloud, i have passed the pits without mesh infront of my intercooler. (i have been yellowed 4times) as for me i am still waiting for approvale for my mods, its taking a life time here, i have had my yellow for about 3-4 months now and i have only driven my car about 1800ks. i have a stock 26 in my gts-t and when they had a look at my shiny painted engine bay, they were like, looks like there has been a lot of work done here. and bla bla bla.
its also good to ask the inspector whats right and whats not so next time you get pulled over and they say something about the mesh or the filter or what ever it is you can say that this and that are alloud.
