Yup, good point! I'll bet mine is the same pump and filter from the factory. Got some decision making tor my two cars, My daily driver is 2006 XF and my "spare" is this 2005 XF. My 2006 needs paint job and was quoted $5K for same color paint job. My 2005 will "eventually" need new exhaust with cat on left bank. I had cut out the old cat and put a used one on. Both run really well. Probably gonna sell one or the other to pay for what it the one I keep needs.
