Hey Guys...

Looking to return my intake system back to stock. Anyone willing to sell their stock Z4 airbox?

Thanks.

I bought this car with a supercharger unit and more installed. I just recently moved to CA and I was looking to put the stock air box in for smog testing purposes. However, I was able to get the car smogged a couple days back with the K&N filter in place.

On a side note...The original owner was able to find the stock airbox and sent it to me. I uninstalled the supercharger system, because the charger needed to be sent to Germany for a rebuild. So, I did try to install the stock airbox back in the car, hoping to get the car smogged with it in, but I kept getting an "EML" warning light and the car would shut down. I even tried the stock airbox with a K&N drop in filter, same issue. I think it's related to the upgraded ECU from ESS tuning and the larger injectors I still have in the car, somehow the car only wants to run with the K&N cold air intake that was with the supercharger kit.

I was also thinking of modifying the stock airbox to act more as a "cold air/ram air" box for the supercharger intake. But, after taking apart the front bumber to uninstall the supercharger, I have decided that I will run some piping and install the air intake down by the brake duct opening in the front bumper...I am hoping this will be a better spot for the intake to get a nice stream of fresh cold air.

Thanks SJL
