How do you change the engine air filter and the cabin filters for a 2004 Honda CR-V?

the engine air filter involves loosening the air tube off the air filter box and unscrewing the air filter box cover. It will take a bit of tugging. To change the cabin filter, you must release the left and right holders for the glove box. This can be done with a screwdriver by twisting the one side, and prying the bit on the other side. Once the glove box flops down, you can see the cabin filter right there. With a bit more prying and tugging, the old part will be out.
