You'll be surprised at what they collect, apart from dust/dirt, mine collected quite a few bugs.
I've changed mine twice in last 30k, last time a couple of months ago.
DON'T follow the replacement procedure where it says to remove wiper arms. You don't need to and besides the damn things don't want to come off anyway.
You just need to remoce the louvred black piece on the passenger side that sits between the windscreen and hood. Loosen the screw on the drivers side louver too (the screw in the center, where the two louvers meet) Getting the louvered piece out takes a little tugging & twisting but it's not too bad. When it's out you will see the filter.
Any probs...post here or pm me.
~$8 from Autozone and don't let them bs you that they don't make/stock them. They do, make them look it up on their system.
oh yeah...thanks for the tip on the Regane Gumout additive. I can't believe the difference in my car.
