Spark plugs for N20 F25 x3 Engine?

slowblackx3f25 · 11-24-2020, 05:14 PM

Hi all, I hope you all are doing well.

I changed spark plugs on my dad's 2017 x3 couple months ago (80,000KM), and the x3 is at 108,000KM right now, and I want to change the spark plugs again, but I don't know which ones I should use...

The ones I had put in at 80k is NGK... but I don't know which ones exactly... I lost the receipt so I don't know which NGK plugs I put in... so I'm hoping one of you guys can write down which NGK spark plugs I should be using for my dad's x3 2017 F25 N20 Motor... any suggestions?

Please let me know ASAP.... I don't use auto off/stop feature as it doesn't feel right unless i'm in a huge drive thru line up... my dad does use it allll the time.

So I feel like I should change the spark plugs even though it's only been 20k since the previous spark plug swap.

Please let me know which NGK spark plugs to use on the N20 F25 x3 engines.

Thank you!!!

Go to supplier site such as FCP Euro, plug in make/year/model of your car and you will see plug offerings- suggest you stick with Genuine BMW or OEM spec plugs.

I just changed my wife's 2017 X3 28i last month. NGK is the original OEM supplier. I used NGK recommended plug ( info on their web site as well). If you buy thru BMW it is the same exact NGK Iridium plug just with BMW logo stamped on the ceramic portion. These plugs are rated for 60k US miles. I replaced her's at just under 60k miles. They were ready for replacement but were far from extended service life. With your dad's vehicle now approximately 20k miles post change, there is no need to change them even using the stop and start function., unless you are having symptoms of bad plugs, rough idle, misfire etc. This could be ignition coil packs as well. NGK has a replacement unit as well listed on their website.

Also spark plug gap is .032 in and torque is 18 lb ft. Pull the plugs and inspect them. Re gap if needed. There should be no reason to replace them.
Good luck.

28,000 km is roughly 28% of the plugs life. They should be changed around the 100,000km mark. In this case the next change would be around 180,000km or a little earlier.

Got it! I will do this when it's time to change the spark plugs. Thank you for your input and your time! Highly appreciated! Take care.

Yes, you are right, I should inspect the plugs if anything before purchasing new plugs.
I don't see any codes thrown, and there isn't any issues with throttle response, and drives fine.

I just want to stay ahead of maintenance, even though it's my dad's BMW.

Thank you for all your feedback! It helps us all! I appreciate the time and support. I hope this thread helps another F25 x3 28iDrive owner/driver! Take care and be safe.
