P.S. There're also Dinan air filters that flow even better than x5m, and surprisingly they fit lengthwise and widthwise (one of our forum members installed them, but wasn't been able to close the lid), but they are too high and stock lid won't be closed - they need Dinan lid - which goes for $1k lol. if not for the lid issue - I would have gone for them (they are like $130 each).

I doubt the third party manufactures are going to be equivalent to X5M filters. Maybe size but not on the bench flow. Plus I bet they are the same as 50i filters. K&N makes a set for both but it's the same filter and it's only the size of the 50i not the M.

Yeah I actually messaged onfirex5 the other day cause I seen his Flowbench testing. I asked if anyway possible they would fit without notching the airbox ans he said no.

I might get a spare box lid and try it out anyway. Thinking about cutting and riviting on a taller top.

Did you click the links it's the exact same filter as the x5m the normal 50i filter looks totally different, just like the K&N look like normal 50i filters. And just because it doesn't have the same "BMW" stamp has nothing to do with flow it's a basic paper media filter and they all utilize the same type of material.

The BMW filter is not made by them but a third party whos parent company is probably within one of the companies I listed.

Here are different filter company tests:

I did and the link only takes me to a page to get me to register. No images of their filters. Yes I'm aware bmw doesn't make their own air filters. They don't make much of anything on their own. Design it and pay someone else to make it for them is pretty common. Sorry but I'm still skeptical unless their flow tested. Only reason why most here install the M filters over stock cuz it's shown they flow much better. Hey, You may be right. You may not.

I agree with Maverik, not enough data (yet) to be sure. Would be awesome if someone could get them on a flow bench or if the manufacturers had some data available.

The material is going to be the same with the 50i vs X5M the increased 14% flow comes from the larger surface area size of the media.

If I go to Autozone and order the X5M filters and they look exactly like the "normal" X5M filters then they will undoubtedly flow more than the 50i filters.

I know the oem filters are made of the same material. That's never been disputed.

And only one way to tell. Order them and get em on a bench flow.

The new part to replace the POS that cracked is light years better and what should have been installed from design. Placing this $10 piece of plastic on top of the turbos to run hot oil through is disgraceful and I just don't feel like I should be paying for the new replacement part. I'm very disappointed in BMW and this vehicle with the $100k price tag.

It's now made of thick rubber!

Also love the rust I see building up on the what I think is the turbos.

I'd love to order that part! I'm going to order the X5 M spark plugs & have my local BMW dealer replace them and it'd be great if they could replace that tube while they're under the hood!

Hello everyone,

Sorry if this may have been covered before but my 2015 X5 50i is nearing 60K and dealer / key fob is recommending plug change among other items. I need to look closely but I think they quoted $600 for plugs alone. I am hoping it's the coils as well. is this the going rate at the dealership? Thanks

You can ask them for a break down. But I doubt it includes plugs.

It's not hard to do yourself.

I ended up going w/ the X5 M plugs & did the BPC tune yesterday. I'll keep an eye out for misfires but checking any codes each week. Bob at BPC said that he'd go with NGK since he's seen issues w/ the X5 M's. Stinks b/c I paid a dealer to do the install so hopefully they stand the test of time.

I think you'll be good. I got the X5M plugs although I haven't installed them yet. I think the X5M puts out 22+ psi stock so should be all good.

Looking to address a full throttle stutter on my 50i (w/50k mi). Went to the dealership and inquired about plugs and coils. They printed off a quote based on my VIN:

Coil (12-13-8-647-689) $123.09 = $984.72 (before tax)
Plug (12-12-0-040-581) $31.64 = $253.12 (before tax)

Total for parts $1,237.84 (before tax)

I think I'll find another source.

BTW, great info in this thread folks. Thanks a ton for sharing!

Buy them your self there ripping you off ,I found coils which are Bosch but don’t have the bmw logo so not made for bmw and there $20 each at Rockauto and Burgermotorsport has the Ngk plugs for $14 or I have found factory BOSCH plugs for about $8 and the same plug with bmw log there like $22.

[CT335xi]

Just for reference I’ll post the part #’s I have for Bosch for coil and plug -
These are factory Bosch part # - Coils # 0221504470 and plug is
Zr5tpp330a. Bmw uses a different part# but it’s the same only his has bmw logo stamped on it.

HOLY $$$hit!!!!! Just for parts????? I bought 7 coils off of ebay for about $20 each. The dealer changed 1 which was causing the problem. So I decided to change the other 7 myself thanks to Maverick's DIY. The X5M plugs were only $31 for the set of 8 at the time so I bought 2 sets. I think the recommended plugs from BM3 are about $18 each which still comes out cheaper than $253. Do some research online and i'm sure you'll find much better prices than the dealer. If you have a local Indy shop, i'd reach out to them as well. The install isn't bad at all. I'm not mechanically inclined at all but the DIY is step by step. The hardest part for me was getting the old coils out, mostly the 2 closest to the firewall. I was using my finger... it's much easier with a thick piece of rope that fits through the loop.

[Teufelshund]

Yeah, for sure. I was already there for an oil change and just swung by the parts counter out of curiosity. To be fair, they did offer to grant me a 10% discount which slashed the price all the way down to... $801.04, lol
$54.07 sales tax brought the total to... $855.11.
I realize these are luxurious supercars but c'mon, we're talking plugs & coils here.

[Teufelshund]

LOL, sorry - promise I didn't take it upside down.

[mikew2069]

Finally got around to changing my plugs. My stock plugs were at 0.032in/0.81mm. I put the X5M plugs at about 0.023in/0.58mm and wow what a difference. This thing pulls hard now like it should. Wish I would've done this a long time ago.

I'm going to change my spark plugs ASAP since I have 46k miles on my 50i. Should I also have my Indy replace coils?!?!?

The coils are really easy to replace you can do them yourself, like someone mentioned get them at Rock Auto like $19 and change you can get all 8 for under $160 . If someone’s doing your plugs there will not be a extra cost to do the coils as you have to remove them anyways to do the plug.
