While I'm not sure how different assembly materials would affect sound, I'm guessing his intake sounds similar to mine. Nevertheless, yes, proven dyno numbers would be helpful before I consider spending almost twice as much as my current setup.

If you'd guys would like to setup a groupbuy with a special price, you are more than welcome to. Just like our other intakes, everything hits the advertised power. For the graph above, we did not remove the car from the dyno. We made the pulls, shut car off, removed intakes, installed new intakes, made new pulls. This was done in a matter of 20-30 minutes at most. Not testing on different days, different dyno, or whatever else you can do to adjust the numbers. If there's any doubt our intakes don't produce withing +/- 5whp of advertised power, we will gladly take them back. We have yet to have a customer return a set of intakes because they did not make advertised power. Id argue our advertised numbers are on the conservative side if anything. -R |

Factory intakes on the X5M/X6M don't have a "drastic transitions".

Contrary to your belief, the stock intakes actually do have drastic transitions because of the filter style, the filter is a very long and narrow piece which causes the flow to diverge and converge. The filters are also very deep which creates a lot of resistance to the flow. Here are what stock filters look like. -R |

Does any part of your intake rub/touch (or get close to) other parts of the engine bay? If so then will you supply rubber/foam inserts to prevent scratching or worse? Also, stock vs new intake inside & outside cabin video's to hear the induction noise difference would be great. Is the noise that noticeable?

They're going for around $1300 and RK has a person on his IG that has a video of how they sound. While mine aren't made by RK, I can say with confidence you'll feel a difference and you'll 100% hear one since I can with mine.

Ordered my intakes for the X5M last week and Raza at RK Autowerks was great to work with. I would recommend anyone to this company as he was very knowledgable about the product and very professional. Great company to work with, would recommend to everyone!
