How do you replace the air filter located on a 1996 Buick Century?

yea you pop the hood, facing the engine on the right side towards the head light there should be a black canister with a wing nut on top. Unscrew that the lid will come off and just pull it out and put a new one in. I like how there is a guide for the ait that's goes under the brace to the head light. I have a K&N filter and soon to get a ricer one. It sounds good under high acceleration.
