One of my friends told me before installing your intake disconnect the battery terminals, leave it like that for 4-6hours. After your intake has been assembled added on to your engine, connect the battery terminals, start the engine, and your good to go. He said it's like doing a reflas, cause it reprograms the ECU to the new air flow, thus giving you the best HP gain. Is that true?

 

you dont have to disconnect it for 4-6 hours...actually, you dont have to disconnect it all

 

If you are messing with any electronic sensor, MAF for example, it is always a smart idea to disconnect the battery.

 

 

You should disconnect it but not for the reason your friend states. The ECU is constantly adjusting to actual conditions so in a way it is constantly learning. I know there are some who might disagree with me so it's just my $.02. Either way, disconnect and you are covered - won't short anything out by accident, or zap yourself.

 

Def a good idea to disconnect. Just remember that it will reset your trip meters, just in case you are keeping track of anything. Also radio presets and time are gone. I know it's minor but I just thought I would remind you. I was using both of my trips for record keeping, forgot to write them down.
