This product, I believe, has been out in the market for a while now. I somehow doubt that it'll give any significant performance difference, although I must admit that I cannot confirm that because I've not tried it yet.
What I've tried is performing a DIY K&N air filter open pod. At least in that, I could feel that slight difference in pick up power.
If you've tried that Stromberg thing, do let us know what difference there is. Have fun.
Here's the link.
