But could be M52 with an M50 intake manifold swap. | | | 06-28-2016, 09:41 PM | #5 | Junior Member Join Date: Jun 2016 Location: Cincinnati Posts: 17 | Would it help if I take the cover off? | | | 06-28-2016, 09:45 PM | #6 | Junior Member Join Date: Jun 2016 Location: Cincinnati Posts: 17 | Also I see a lot of "m50" engines that vary in size. What size do you suspect this to be? I'm asking because I plan on doing my own maintenance and tune ups and upgrades and want to be sure that I am purchasing the correct parts for the correct motor. Thank you so much for your replies and insight. | | | 06-29-2016, 02:02 AM | #7 | Junior Member Join Date: Jun 2016 Location: vancouver bc Posts: 6 | They all share the same head I believe. More than likely it is a 2.5L.

I have read here that mobile 1 high mileage is recommended but what plugs and at what gap should I use. I used to mainly own jap. Cars and used denso iridium, and I'm kinda finicky about using the best I can get. So what plugs do you guys recommend, and thanks for all the input | | | 07-02-2016, 04:49 PM | #10 | Senior Member Join Date: Jul 2007 Location: norcal - 94590 Posts: 3,186 | NGK plugs are the best I've used for BMW's __________________ James 95 active w/leather interior and sport interior conversion, Vaders, full M-Tech exterior conversion.
