ok i bought an 04 rx8 about 6 months ago and when i bought it, it had a typhoon intake v.1 on it already. now my question is what do i have to order from the factory intake system to be able to swtich over intakes like the version two k&n intake system so it will idle right? Or can i just order the new intake and just put it on and not need any other parts from the factory air box?

 

If you want to switch to Typhoon Version 2 (Cuz seriously Version 1 suck ***), all you need is the mesh, and you can buy the part from our forum vendors.
