charvezding 0 Report post Posted January 17, 2011 Hi guys I'm about to get dirty and change the oil and air filter on my 1987 525e myself Trip down to supercheap for a ryco airfilter and oil filter seems to be the way to go. Car has done about 180,000km so i'm thinking of putting magnatec in it. Any thoughts or recommendations? Cheers Phil Quote Share this post Link to post Share on other sites
