I just received an aFe stage 2 CAI. I'm going to attempt to install it ASAP. I read somewhere that it is necessary to disconnect the Neg. terminal of the battery. Instead of doing that, is there a fuse that can be removed? If so which fuse? Thanks in advance for any reply.

Im sure Ive probably done something dangerous, but my last three cars Ive put CAIs on them and havent disconnected the battery or pulled a fuse. Somebody needs to explain why thats really necessary for this particular mod.

I didn't do either when I installed my JMB CAI. No issues and I didn't expect any as nothing really changed in terms of tune or airflow. One thing I did is I bought a new IAT sensor as I left the stock IAT in the stock airbox in case I need to put it back on for a trip to the dealer. (Don't want to jinx myself)

I just plugged the new IAT into the elbow on the CAI and plugged the harness back in. I didn't feel like that would be causing any electrical issues.

Now, I could see disconnecting the battery if you were doing a throttle-body change or working on the computer box itself, that would make sense.

I think this is more for safety than anything else. However, when you disconnect the battery for a long time, it'll reset your learning adaptives which can also be done by pulling fuse 11 for 10 seconds.
