M Frt Bumper Cosmetic Surgery
Installed my M Frt Bumper today. It was relatively simple and will post a DIY later when I get all the photos organized. So about $750 in parts including the Performance Grills & "M" air duct parts. $300 for paint. My labor 6 hrs.

Where did you order the bumper from? Cheapest I found on Tischer was in the high $900s. Also, who did the paint and install for you? I am looking to get the rear M Sport bumper next.

Thanks. I was going for a more aggresive look with the performance grills. Thought about putting in the grey grills with the gloss black surrounds. But decided on the full mean performance kidney look. Kept the stock grey/chrome kidneys so I can play swap later if I get tired of the all black.

Make sure you get 4 PN (51747192197) expanding rivets as the factory items are unusable after removal. The factory items are more like a plastic pop rivet where the stem shears off at installation. These are used to secure the lateral air ducts to the vehicle.

Thanks for the initial write up and pictures. I have an M front bumper that I picked up second hand on ebay that's in great condition, just needs painting up in Black Sapphire metallic.

51747903729 - left lateral air 51747903730 - right lateral air duct 51747903731 - lower air duct If you have a N54 with oil cooler you also need a specfic duct for the oil cooler. 51747903727 - oil cooler air duct It's about $100 worth of plastic. Less expensive than mods or worrying about cooling IMO.

Air flow is not helter skelter. If you ever remove the bumper cover you will understand how BMW controls the airflow to the radiators. They seal things up pretty darn tight to ensure what air goes in through the grills in the bumper cover goes through the radiators. If you use the old non "M" specific ducts you loose airflow over the radiatiors as the air is no longer trapped/forced through the radiator. If you leave them off even worse. The floor of the car and engine compartment are pretty well sealed. The belly pan utilizes NACA Vents to duct air into the engine bay. It's all about differential pressure. If you don't have sufficient air flow over the radiators you loose cooling. FYI - the lower grill opening on the "M" bumper cover is 116 sq in -vs- 100 sq in for the non "M" so I would expect some added cooling for the radiator, trans and inter cooler - all things considered. More air flow takes more heat out of the systems.

HerrK, Thank you for these part numbers. I am going to check my parts order for my M bumper and make sure I have them. If not, I will order and install.

HERRK:
Thanks for your post. I read with interest as I damaged the under side of my bumper cover and I'm thinking of removing for repair and painting. How difficult is it to remove the bumper cover? Is it as simple as removing the screws across the top, bottom and in the front of the wheel wells? Do you have other pictures of the bumper cover removed that show connecting points? Finally, as the bumper cover was painted off the car, was there any trouble in the paint matching the car? Thanks of sharing info. |

a. Wheelarch Trim b. Underhood Shield c. Frt Bumper Trim Panel 1. You have to put the car up on a jack or jack stands - both frt wheels. 2. Remove the frt wheels. 3. Remove the frt engine tray cover. (BMW call this "Engine Encapulation, frt" on real OEM diagrams). 18 or 19 small hex head screws (all the "small screws" mentioned - require an 8mm socket). 4. Remove the left & right frt air dams (BMW calls these "Covering" - Item #2 on "a"). 3 small screws ea 5. Remove the left & right frt wheel well liner. 3 screws and 2 plastic nuts ea (10 mm hex head). The ambient temp sensor is installed in the left frt wheel well liner (center of photo). Just disconnect the plug and leave the sensor installed in the liner. Once all these plastic parts are out of the way it is fairly simple, not that any of this cover removal is difficult, just takes time. Now it is simple. 6. Under the hood. Remove the Frt hood gasket which covers the 7 'Torx" (Size 30) screws. 7. Remove 6 of the 7 Torx screws on top. I loosened but did not remove the center screw to keep the cover in place. 8. Inside the left & right wheel well there are 3 small screws on each side near the reflector. These are the screws that control the adjustment of the "gap" between the hood and bumper cover. Remove the screws. 9. Hold on to the bumper cover and remove the final "Torx" screw under the hood. Note the cover will not just fall off. Let it droop down and gently pull it off. Paint matched fine. Wil post more pics later.
