Welcome to SAU dtrants
Just put the new maf onto your airbox, plug it in, and start driving.
The maf od is 3" so any 3" pod will fit. But you will need an adaptor. They can be found online or ebay etc.
I used to use a k&n panel filter. I washed it with cold water then let it dry and it was fine for 6 months until I changed my setup. If there are any remnants of oil on the filter and it does make a film over your new maf, get some contact cleaner and spray the maf wire and it should clean it up.
