I changed my last weekend... actually my mechanic did.... I felt stupid.. because it seemed so easy to do it that I could do it myself...
But u have to lift the car... it is located in the back o f the car... close to the back left door....
IT is easy man... lift it first, take a look at... breath deeply.. and just do it !!
By the way... make sure u have the new clamps or straps... to tie it back on... I bought my filter at the dealer, and it didn't come with it, so my mechanic had to tie it with the old straps... something like that.. you'll see it...
