    I think they drop ship from BMS, though. So that still won't work.

    Does anyone know the diameter of the piping on the Agency power intakes? Looks bigger than K&n for example.

    I just emailed Sal, and he said he is able to sell/ship to CA residents.

    If I remember correctly, @Terry@BMS claims that the outlet of the box is a restriction. The piping from the box to the turbo is supposedly OK. It would be interesting if we could better identify and rectify that, in my mind, for those who don't want to hear the intake and blow-off noises. There could be a cheap solution, too. But I've not yet looked into it - winter here!

    Received the BMS intake yesterday. Fast shipping as usual from Sal. Will be installing this weekend and the k&n typhoon will be listed in the classifieds soon.

    I wanted the BMS from the get go for cosmetic preferences and to stay consistent with my jb4, but I was having difficulty sourcing one in CA (stricter laws I suppose). I found a K&N and it seems fine and I doubt I will notice any difference compared to the BMS.

    So I actually had a DIY intake system which is great but also got a bms intake... haven’t put it on because it needs powder coating and the cones are much smaller than my DIY.. so I’m going to mess around with my set up and see if I can utilize the piping and shield from bms and somehow use my larger red cones which look really nice against the yellow car ... but i was wondering how the sound is on the smaller cones ? Is it still pretty loud ? My large cones are like jet engine sound haha

    What color are you powder coating the pipes?

    Ill share my thoughts once I install the BMS. At a glance, the BMS filters do look smaller compared to the k&n cones. k&n over stock, its noticeably louder, definitely hear a jet like whoosh under WOT, followed by the blow off sound.

    Probably go with yellow on the piping and possible yellow on the shield or maybe a red or black... depends on how my set up works out.. might not even bms stuff.. I want to but it depends how everything fits

    Best of both worlds, I’ve had no issues with it.

    You just opened an additional "inlet" on the "outside" of the filter housing?

    @eflyguy

    You got it, opened to the fender side away from the engine to keep cooler temps flowing. Kept low end intact vs the DIY SRI set-up.

    Car stays relatively quiet with some additional whistle.

    My impression was that the restriction was on the turbo side of the filter. If you've cut an opening on the turbo side of the filter, you've just opened your turbo up to all kinds of dirt, etc., even water.

    Did you find a restriction? Is the outlet side of the box smaller diameter than the inlet? Sorry, I'm just not getting what it is you're trying to tell me.

    Where he cut the hole still goes through the oem filter first.

    Then it doesn't fix what I thought @Terry@BMS was saying is a restriction about the OEM intakes.

    I think terry said the restriction is not in the pipes but before the intake box so that hole would help with the restriction terry was talking about... that’s what I think at least. Only issue is thing would pull in hotter air under the hood but most of the intakes do that anyways.

    The top photo was working on a DIY heatshield, it helped but I can do better and scraped the idea.

    If there is any restriction on the turbo side of the box (top half) it’s minimal. There is, however, a noticeable step down on the snorkel side (pre filter) that is a restriction.

    The OEM filter looks to have sufficient pleating to hold a descent flow. Someone would need to test that to be 100%. The stock snorkel probably narrows to ~ 2x3.5 inches rectangle. Opening the opposite of the box - in theory - opens immediate available air on initial punch and then keeps cooler IAT’s when moving. I’ve seen identical IAT’s but improved low end power vs the totally open round dry flow SRI design.

    What Terry’s design does do is similar, enlarges available free air area for better throttle response compared to the stock airbox. Being that the BMS is totally sealed it make help keep temps closer to the stock airbox as well. The benefit of my alteration gives a descent amount of the positives with very little negative. Throttle response is there, heat soak is pretty much no worse than stock, more flow is available if needed up to the max the stock filters can provide.

    The red circled area is a restriction area.
