I haven't been able to hook it up yet, I'm waiting for all the screws that got lost in shipping. I can't wait tho! I'll let you know how it goes. Ithink volant keeps the resinator
but I hear it's still a really good kit. Let me know how yours goes. I got the volant #15635 kit.

I have a 07 and I installed the airdoc and a K&N filter
Works great, easy install, well built
You should be very happy with it

It adds a new spin to vehicles with limited air flow to the original filter location. Offers a cold, dense aircharged for improved horsepower, torque, and fuel efficiency.

Air Doc
 

I bought all the parts for the airdoc for my 07 H3. Determined some of the parts didn't add much improvement over stock. Ended up essentially just using the Spectre (K&n-like) filter.
No performance difference perceivable. Save your money.
