Question for you guys. I'm putting in a K&N filter in 07S. With the older cars, you had to disconnect the battery for a while and let it pick up the new air/fuel reading. On this car, being that the filter really is not going to make much difference (just doing it for better filtration/dust reasons), do I need to disconnect the battery or just drive it and let the computer take in the reading and adjust itself? Thanks.

 

just drive it. The computer always is adjusting

 

well if you carry that damn manual around with your navi code and radio code then by all means unplug it... lol.... it is just a filter dude you'll be alright just pullin the old switcharoo on it...

 

I felt like a few wot runs and the computer would figure it out on its own.
