BMW M4 Spark Plug & Ignition Coil Replacement DIY (2014-2018 BMW F82 M4, F80 M3, F87 M2)

►The turbocharged S55 engine found in the M3 and M4 is a stout tuning platform for anyone looking to make power, but it requires the same maintenance that any other BMW engine would. Replacing the spark plugs and ignition coils is a regular part of maintenance and will play a significant role in how your M3 or M4 performs on a daily basis. Turbocharging puts a strain on the ignition components, and when they begin to fail, you'll experience power loss, worse fuel economy, and even rough running. BMW recommends a service every 60,000 to 80,000 miles, but you may want to shorten that interval if you've increased your power output.
Servicing your BMW's ignition system is very straightforward and won't require any special tools. It's just a few simple steps and about an hour's worth of work away from reviving your S55's performance.

At 17:10, the tool size to remove and install the spark plugs is a 14mm, 12 point socket.

[@zildog]

Finally, my good people … something relative to the F87.

[@fcpeuro]

More en route!

@@fcpeuro Yes please! More content for the M2C also please, as more of us are beginning to need different services and are buying parts from you guys.

Omg the amount of things to remove to get to the spark plugs is insane, bmw really doesn't want you working on your own car, their engine packaging engineers are insane. My previous car, solstice gxp with 2.0L turbo with direct injection, here were the steps to remove the plugs 1. remove plastic engine cover 2. disconnect connectors on coils 3. undo one screw on each coil 4. pull coil 5. unscrew spark plug 5 minute job, same for pulling the valve cover, 5 minute job I might regret buying the new m3 😂

Just got an M4 convertible, beautiful vehicle but the only thing really accessible to maintain is the oil filter. Why owners need to remove engine bracing simply to replace an engine air filter is beyond silly. I appreciate your thorough step by step instructions and assisting DIYs like myself. My only suggestion is modifying the video with a safety note. When dealing with electricity, make sure to disconnect the battery located in the trunk. Similar to your other tip, block the locking mechanism in the trunk with a shop rag, so that you avoid shutting the trunk without power...just sharing a lessons learned, pretty easy to access the trunk with a convertible, couldn't imagine doing it with non-convertibles. Keep up the great work! As a fyi - in Seattle, Washington a BMW spark plug replacement is $1500 in 2024.

Let's get some more diy videos related to the f87 (M2c)!

👍😎

[@drbvac]

Agreed with following comment as it is a special purpose socket and no regular of any size will fit the OEM plugs. Right in the middle of doing mine I had to bum one off my mechanic - other than that excellent instructions and an easy DIY. You do need to have a pretty good assortment of tools though 😃

[@legambaz]

A well deserving video considering the complexity of the engine bay design. Unfortunately for an engineering freak like BMW, they churned out such a maintenance unfriendly design. Half a day just to remove things before touching the plugs. THey probably have a dedicated dept just designing brace bars for their cars. Layers of plastics to prevent heat from escaping. No wonder their cars predominantly have loads of heat related issues. I wonder how much the dealership charge for a job like this.

[@fcpeuro]

Thank you for watching! It sure did feel like we took a lot out before getting to the spark plugs 😬

One of the few vids where anti seize is not used. NGK says no Anti seize

[@fcpeuro]

No Anti-Seize!

[@nickbarba9809]

silverstone..... yes

[@F80_kev]

so there is no need in disconnecting the battery?

[@johnnyblue4799]

I don't get what's so special about those two bolts that they need to be torque to yield. And I hate torque to yield hardware. Imagine you torque them down and then you realized you forgot something and you need to remove them. Now you need two extra.

[@gixxerhoff7502]

I will tell you I’ve had them out on my car at least a half a dozen times and have never replaced them.

😓
