who lives in my air filter compartment under the hood?
SPONGE BOB SQUARE AIR FILTER.

I often read the forums but do not post, I had to contribute.


Used a few parts catalogs last week (not sure which) which lead me to an ebay listing of a cruiser part. part numbers:
1-05066076aa (search 05066076aa filter)
list as mopar. also has a number that looks like the factory run: 3118-631

I asked that the seller update his listings, he has not:

Seems to be running smoother. I had cleaned it previously but it never quiet had the same shape.
