Overview:
Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51375. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency.
Designed to fit the 2008-2011 BMW 528i, 2006-2007 BMW 530i, and more, this direct-fit catalytic converter also interchanges with OE parts 18 30 7 541 848, 18 30 7 541 849, among others. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Was skeptical but it worked out of the box
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
Was skeptical at first but decided to pull the plug and get the m4 laptop with 3 years of apple care and it works. Haven't even opened an email or anything, laptop was still fresh out of the box. When I remembered I bought apple care and decided to check. Applied instantly as far as I know once I linked my apple account on the first boot up with internet! Good stuff

DO NOT PURCHASE WITH YOUR MACBOOK OR OTHER APPLE DEVICES
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
I bought this along with my MacBook. And here is why you SHOULDN'T:
1. They NEVER sent me an AppleCare+ Agreement. You will only be able to download a General Terms & Conditions file.
2. I bought: AppleCare+ for 13-inch MacBook Air (M4) (3 years) and in the General Terms & Conditions that I downloaded, looking for my AppleCare+ Agreement #, it NEVER mentioned Macbook Air as a covered device. It was meant for other smaller devices, which is why it's cheaper.
3. Like I mentioned, since I never received an agreement, I never got an agreement #.
4. Since this AppleCare wasn't actually meant for a MacBook, it didn't connect automatically to my computer. So when I went to talk to Apple and Amazon, without an Agreement # you can do ANYTHING.
If you purchase it, read through your General Terms and Conditions and find an excuse to ask for a FULL REFUND. Since this didn't cover my computer, I was thankfully able to get one, but it was a pain trying to talk to customer support and apple.

It worked! Apple Care was added to my device when I received it!
Style Name: MacBook Pro 14" (M4 Pro/M4 Max), Configuration: 3 years
I purchased an MacBook and AppleCare+ at the same time. A day/two after the purchase I received an email from Amazon that the AppleCare+ was in software and go to digital download. When I downloaded it was just the agreement. Then I started reading all the negative reviews on nightmare experience with Amazon and AppleCare+ not being added. I was very nervous and mentally prepare for the nightmare that lie ahead which having to call Amazon multiple times and then having to call Apple multiple times. To my surprise, right after Amazon delivered the MacBook (I got notification your item was delivered) I got another email from Amazon that AppleCare+ was added the laptop with agreement number and serial number of the laptop I received. I checked Apple's coverage site and sure enough Apple site showed AppleCare+ coverage tied the MacBook. I didn't even open the box or turn it on and see the AppleCare+ coverage. Hopefully this gives some insight to future buyers of AppleCare+ from Amazon!!!

DO NOT PURCHASE APPLECARE+ THROUGH AMAZON (Please read before making a decision)
Style Name: MacBook Air 13" (M4), Configuration: 3 years
I rarely write reviews like this, but DO NOT PURCHASE APPLECARE+ THROUGH AMAZON.
Just over a month ago, I purchased an Apple MacBook Air (m4) with AppleCare+. The AppleCare+ wasn't populating on the laptop, so after calls with Apple Support and Apple Agreement Administration, they found that AMAZON sent them the approved agreement with the device serial number then abruptly canceled it the following day. This happened over a month ago, and I was not notified nor have I received a refund.
I would not have known it was canceled if not for Apple Support and Apple Agreement Administration.
The only recourse is to receive a refund from Amazon--which is NOT automatic, I am fighting for this--and purchase AppleCare+ directly through Apple. Had all this taken place after the 60-days purchasing the MacBook Air (I'm currently one week short of this deadline), then I would be SOL on being able to cover my device.
PURCHASE AT YOUR OWN DISCRETION/RISK AND CHECK THAT APPLECARE+ IS APPROVED AND ACTIVE ON YOUR DEVICE. Otherwise, play it safe and activate directly through Apple.

Worked fine for me 🙌🏽
Style Name: MacBook Air 13" (M4), Configuration: 3 years
I read a lot of comments that said there was an issue with their purchase of AppleCare+, I did not have any of those experiences. AppleCare+ was on the laptop (MacBook Air, 13-inch 2025) automatically. I received an email with my confirmation of AppleCare+ coverage, along with my agreement number, product serial number and expiration date. There was nothing I needed to do on my end, because as I said it had already been added to my computer and attached to my iCloud account. — I hate that there are so many bad experiences and hope everything works out for anyone experiencing a nightmare but I can only recommend based on my experience, 10/10.
