After a new engine block was put in by the dealer 3k miles ago..... went to do a simple oil change yesterday. grabbed my castrol edge and my usual k&n hp- 2009 oil filter. i go to put the new filter on and it wont grab. thought the threads were messed up when i noticed the hole on the filters were different sizes. grabbed a micrometer to measure. ones 3/4 inch and the new one is 22mm. how could they of done that if they grabbed the same block. its the 3.7l motor. i ended up putting a short and stubby filter on there made for a ford and it seems to be holding. the old filter that came off was the same length and width as the 2009 K&N i always put on but the threads were diff. any explanations on why the dealer would do that and whats a good part number for the 22 mm filter?

 

Try doing a cross reference check on the OEM filter and see what comes up.

 

I tried cross referencing it online and got nothing. took it to the auto parts store and they couldnt cross reference it either. im thinkin it might be a new filter and the block might be some updated model of the original 07.

 

What brand and numbers are on the filter??

 

09 up uses a different filter with 22mm thread.

Damm beat me too it.

 

Oh now that would make sense if the block is an 09. i wonder why i didnt check that k&n number at the store. i started randomly checking parts to find the right one. thanks for the info. just an fyi the mopar part number that came from the dealer is 05184231aa.

 

the mopar number is mo 231 the 05184231aa is the chrysler number
