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?
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.
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.
