I just got a 01 Civic ex the other day and was checking all the levels, etc. I tried to open up the case for the air filter but it wont open. Others cars I've had just have clips that you open up but on my cars it wont budge. Do i have to unscrew anything? Thanks in advance!!

 

Can't really help, can only say I have a "99" and a "02" and both just clip! The "01" must be different. msn

 

You have to unscrew the bolts on the side of the box and the one in the middle then pull up
I have an 01 too Ex

 

that is odd that for one yr it has a different open/close mechanism.
