Sorry, I mistakenly posted this in the E89 thread.:dunno:
I have searched everywhere but I am unable to find an answer to a seemingly easy question. I have a 2006 Z4 3.0si with sport package. I am simply looking for an oil filter. I went to change my filter with a Mann HU 925 4x but it was much longer than the existing filter. Everywhere I look it says I need this one. However, I did find a couple of sites that said the HU 816 X was the correct filter. It said Z4's with a heat exchanger needed the 816 and those without used the 925. How do I if I have a heat exchanger. I recently purchased this car so I don't feel comfortable just going by what is in it.
Thanks in advance,
