Is there a DIY for this? I'm planning to change the cabin air filter myself if it isn't too hard. I searched and found a thread, but all the links for the DIY were dead.

I found one here, but it's not the most detailed of guides....:http://www.infinitihelp.com/Ownershi...AirCFilter.htm

 

try these:

takes a maxium of 15 minutes. remove the rt lower kickpanel take the 4 bolts out of the glove box. pull the glove box down and remove the clip on panel on the air box. then slide the old filter out and put the new on in

 

Is it the same process for both coupe and sedan?

 

^ Yes, it's the same for the coupe and sedan.

 

Thanks a lot guys. Doesn't look too hard, I'll go ahead and do it myself. Now I just need to go out and buy a filter...
