I finally got around to installing mine today. The install was very easy with the exception of the cramped work space for several of the screws (don't drop one or it's gone forever). This mod can easily be taken back to the stock box and filter in 15 minutes now that I understand how to work faster in the tight space. From a sound perspective I don't hear much more as far a turbo spool goes but I certainly hear a deeper MPPSK exhaust note under heavy load. From a power perspective combined with the MPPSK no doubt this mod is worth the minor cost as it seems to add just a bit more lively punch through the mid gear range. It's a simple equation. Simple install, easily reversible, low cost, better sound, more power = more fun!

I'm wondering if the Agency Power intake would work without issues, in the same way, on the G30 540i. Has anyone had any experience with that? Thanks!! |

I wish you guys would go to the considerable trouble and expense of doing a before and after dyno for these things. Only then can you prove that the change made a difference in performance. I stand by my earlier claims (in other posts in probably other forums) that these intakes make no performance improvement. In fact, they can decrease performance because you are changing the conditions under which the ECM expects to operate. Now, if it sounds better and that's all you are trying to do, then that's fine. Or you think it looks cool. But these engineers know what they're doing, and if they could get extra horsepower without sacrificing engine health by simply putting on a gauze filter instead of a paper filter, then they would come that way from the factory.

Did mine today. I suggest you to unplug front grill shutters (top). And keep in open position.
It will keep lower shutter open too. This will improve cooling a lot. |

I read through this before getting the BMS intake for my G30 540I and after installing I can say without a doubt it makes much better engine sounds when accelerating (I did not expect to like the turbo sound as much as I do but it's nice), I had to go to the dealer to fix my seat sensor (you know the 1) and did not want them poking around and making a fuss about the intake so I put it back to stock for the visit (literally took me 10-20 mins after work), the sound difference is not incredibly drastic but it is enough to make it sound just right to me (I still have stock exhaust with the valve safetied open). For those concerned about hot air there is a simple fix that seems to work well for me, i made a heat shield out of sheet metal aluminum and covered it with stick on heat shield off amazon, added seals to the top edges to minimize air coming from the exhaust area, it takes a bit of trial fittings to get the contours right with the crossbar going over the intake area but it really seems to help because when I open my hood after driving home in 90F temps my intake area is much cooler the the rest of the engine bay.
I am now looking for ways to maximize air intake from the front grill to increase flow, there are scoops sold for 2,3,4 series that go behind the left top grill to increase airflow into the air box but i cant find one for a G30, if anyone knows of 1 please let me know. |
