pcv valve & fuel filter

I want to change the pcv valve in my 98 max with 55,000 miles on it. I don't think it was ever changed before, but i've seen it make a difference in my other cars. Where can I buy it and what part number do i ask for? I want to make sure i get exactly the right part. Thanks!

For the PCV valve, go to AutoZone to get one. Less than $5 bucks. For the fuel filter, get a fuel filter for a 1996 Nissan 300z. It's bigger. It won't filter any better or worse, just last longer for not much more money, you can get it at AutoZone also.

Here's a website with pics that'll help in both installations.
