Local parts store does not have the 2006 cars in their database yet. :surprised What is the part number for a Mobil One Oil filter for the 2006 300C SRT8? I could go buy a Chrysler part, but I am partial to Mobil One filters.
Same issue I had last year with the 05 C, check the dealer for the Mopar #, the C is the same as the 300M, Hemi Ram, Jeep etc. Use the 06 SRT 8 Mopar # which may very well be the same as the C et.al. and buy the proper M1 filter based on that cross reference.
