BMC air filter CDA

[bentai85]

I am considering to install BMC airbox for my car---> the very restricted 4 pot valvetonic engine. Anyone used it before or know anyone who had experience with it? Mike from SWC recommended me to use it.... Because i connected a air pipe from the front of the car bumper to the stock airbox. Need comments and feedback

Ops... the pipe is not connected to the stock airbox. The pipe is there for standby for a new airbox which i am still scouting. Heard Gruppe M has too large a surface area of induction, thus de-powering the car. But this BMC airbox has a even smaller surface area than the stock airbox, with a conical design within to build up pressure... I am wondering if it will boost the HP of my car and if anyone had tried it out before. Can check out at the following link. Carbon Dynamic Airbox

Re: BMC air filter CDA

I have installed the BMC air filter... It really killed the low end torque. But its only from 0-2.5k RPM. The torque starts to kick in real fast when it hit 3k RPM. Its just very troublesome for me when i go up the slope in my multi story carpark... bo lat. And it will be very slow when going through narrow roads... But its definitely better than Gruppe M.

Re: BMC air filter CDA

Installed this BMC CDA carbon airbox for 3 years now, did a dyno tune on the 325iS back in 06. comparing the power output between the BMC CDA and K&N air filter element and stock paper element

With the paper element along with my other mods, i got a 116.2KW at the wheels.

K&N element, 116.8KW at the wheels

BMC CDA , 118.6KW at the wheels

Torque also inreased from 346NM to 401NM

I strongly believe in this Carbon airbox and it sounds great.

Since then, now together with M3 Cams, Car is now pushing 138.9KW at the wheels

Cheers!
