I swapped out my factory intake to a Takeda CAI long tube and the instructions asked to disconnect the battery. I did not see a purpose for this and I have had no issues, might just be a worst case scenario to avoid lawsuits. Can't see a reason why you would need to mess with the battery to change the air filters.

I ended up throwing on the K&N Drop-Ins without doing anything with the battery. Been in for a couple weeks now with no issues (knock on wood).
