I just installed a Cosmo Racing CAI. When I took out the stock air box, I noticed that I had to take out the Secondary air pump tube( the circular looking box just behind the stock box and connected to it) that was attached to the Stock air box. I only took the tube out, and the car seems to be running fine. Does this affect anything about that secondary air pump? The haynes manual, nor the Cosmo manual says nothing about it. Just wanted to know if anybody had any problem with this.

By the way, the car is a 97 318i

If you look at the airflow meter, there is a circular looking box to the right and below. That is the secondary air pump. Before I removed the Stock air box, there was a tube that was attached from the secondary air pump to the stock air box. Now that I got the CAI, I removed the tube to the secondary air pump. I wonder if this does any damage or is bad in any way.

the secondary air pump is only there for emissions - it won't affect the performance of the car at all. Basically it's there because car makers want to be able pass EPA emissions standards - so they install the secondary air pump to inject air into the exhaust gases to thin it out. You might want to just plug that hose up with a golf tee or something and unplug it when you do emissions checks.

The secondary air pump does not connect to the air box...you must be looking at something alse...maybe the snorkle???

The secondary air pump puts air directly into the block through a valve...other side of the engine bay (on my car at least)

I believe the air temp sensor is mounting on the driver side brake duct

Sorry about no photos guys. I have a 318i with a M44 engine. Maybe that will help.

the air temp sensor for the OBC is in the brake duct. There is also an air temp sensor that controls heat to the throttlebody. It's plugged into the side of the airbox and a tube runs back to the manifold.
