2017 Audi A4 (B9) Air Filter Change

[@eddie7167]

Very helpful, I'm planning on doing the same with my 2018 A5 TFSI. I like the fact that the screws stay in the airbox cover instead of disappearing into the engine bay and then rolling under the car 😂

[@ukimonkey1]

Thanks very much for the tutorial! Worked like a charm on my 2018 Audi A5 Cabriolet. The only thing I would caution (I used a K&N E-0648 Air Filter) is you have to make sure the smaller slide friction clips on the bottom are lined up. The first time I put the K&N on, I missed one of the clips; it slid above the grove portion of the clip. Other than that, your video was spot on and thank you again for posting it!

[@redataoussi]

Isnt the 648 for diesel engine? Or does the 648 and 646 are the same?

[@ricardostus2498]

Excellent video. Just a couple of thoughts based on my experiences. The captive screws only take 5 rotations to remove/tighten - I don't bother with a power tool. And if you're somewhere that have leaves fall off the trees, have a shop vac ready to clean out the compartment before actually removing the filter. Mine had a quite a few dried leaves to be sucked out. And after removing the filter, be ready to vacuum any small shreds that might be attached near the seal. And maybe check to see if any debris fell from the filter pleats back into the compartment and clean it again after the install.

Outstanding tutorial. Just got a 2017 A4 Quatro s-line and with this being my first Audi I needed to know how to change the filter out for a K&N which I do on every automobile I’ve owned. Super easy and to me a must do easy mod for all vehicles!

[@Klikklikboom0911]

I purchased this E-0646 for a 2018 Audi A4 and the stock oem filter is definitely smaller than this K&N filter.

[@OldAndGettingOlder]

@soc4me, I have a question about your other video replacing the F150's center console rear cup holders. In the description you provide a PN# ML3Z-1513562-DB. Is this really correct? Could the 'D' really be a 'C'? I'm finding this very similar PN# ML3Z-1513562-CB.

[@KulwinderSingh-rm1jd]

Does this work for 2016? The air filter doesn't open when I try to turn it

[@jameshenderson5385]

K&N do let more air in but they also let more dust into your engine to, so be careful . I always use Febi air filters, much better.

[@oliversun5039]

Thanks for the video. However, when I screw the cover back, I noticed gaps between the cover and the air box. Did that happen to you? Am I installing it wrong?

[@DiamondPilotDan]

@soc4me did you have any change in intake sound?

[@soc4me530]

No unfortunately not

[@goldcoastscent]

Thank you so much for this video! Was looking everywhere to replace my Audi A5 filter with a K&N one. Have you noticed any difference in car performance or sound upon replacing the filter?

[@soc4me530]

Connor Harootunian, as much I would like to say yes, I don’t think it made much of a difference. But still glad I did it. Wouldn’t have known otherwise.

[@justinschraeder8924]

The difference isn’t so much in performance. The benefit is mostly in the fact that it can be cleaned and reused.

[@MotoMario1]

Maybe buy another filter cover and cut some of the plastic on the top away so the sound can come through. I know it is not the best for performance, but it would still have some heat cover around like some performace filters do. I think I will try that out. But first I have to ask the price for that filter cover.

[@Kiss__Kiss]

Great tutorial. Any new content? how's the B9 treating you? any warranty repair? any mods? I've been thinking about a B9 but can't decide on the sedan vs the allroad. Then there's the Quattro-Ultra vs Quattro decision.

[@soc4me530]

It’s been great. No issues so far... sorry, no new content.... I have the B&O sound system and while it sound great, I wanted some more bass. So I added an aftermarket sub.... Other than that I would like to do a tune, but don’t want to void the warranty. Had an APR tune on my last one and loved it.... ya as far as the sedan or all road, think that just come down to the room you need. Both are great.

[@Kiss__Kiss]

@@soc4me530 Ahhh Thank you for the detailed Write-up. Glad the B9 has turned out to be a great and better B8 platform. Then again, it should be.

[@victorlupu3795]

Hei men please please do a video with the oil exchange because I do not understand how to remove the oil filter, it's crappy I can not figure out how to take it out

[@soc4me530]

Victor Lupu I just have mine done at he shop as part of Audi care. So sorry, I won’t be doing that anytime soon.

[@Hazardhemi]

What's the kn part number

[@jakub6514]

Thanks!

[@sreyes1103]

After changing the filter, did you get any intake sound?

[@soc4me530]

Unfortunately, no. I was hoping for that as well. I even removed that piece of foam Audi put in the intake box. Still nothing.

[@gray_a5]

I know I’m two years late, but remove the air box and hang the plastic cover that holds the filter against the rubber bushing or look up “Audi b9 turbo noises”

[@MichaelRoy777]

Could you please tell me how much does it cost that K&N air filter? Thank you for your answer.

[@justinschraeder8924]

They are about $70 USD.

[@tinnguyen143]

After how many miles are you supposed to change the oem filter?

[@timhiggins6212]

Every 50.000 miles

[@MichaelRoy777]

Just wrote about that in one comment above, I am not sure but in my country the Audi enclose themselves on 10 000km. I don't know why is it like that. If someone can tell me why is this the rule in Europe and why in USA you can change it on every 50 000 miles i would be very grateful for the answer.

[@kiddcisco]

@@MichaelRoy777 change the air filter as required based on enviromental conditions, if the filter looks clean continue to use it, 10000km is too soon, you can go 20KM easily or replace every 2 years

[@Greecus]

Hi guys Did anyone can tell me wich is better K&N 0647 or K&N 0646 Thx

[@eduardohammerschmidt5195]

I had this confusion and bought O647... but it doesnt fix on my audi a4 2017/18 b9 190cv! I had to return the item to the store, and now i`m little worried about using 0646 and doesnt fit again man If anyone can tell me your experience from 0646 and 0647 i would appreciate... thanks

[@redataoussi]

As for the gas mileage how have it been si far?

[@soc4me530]

It does great. Freeway cruising at 5mph over the speed limit, I’ll get 35 plus mpg. I few times I have gotten 40mpg.

[@MichaelRoy777]

I have Audi A4 from 2015 but B9 model and I will tell you if you are driving this car nicely, that said by the speed limit, in my country with good fuel you can pass more than 1480km with full tank. Because with nice driving the fuel consumption doesn't go over 3 liters per 100 km. This car is a beast as for the performance of how long it can go with a full tank.

[@paull3179]

@@MichaelRoy777 I only get 400km max on my S4. Highway would be much more at constant speed so maybe 550 to 600.

[@jolo4204]

So how you likin this car? Is it reliable? Any problems? Im thinkin about getting one this month

[@soc4me530]

It’s been a great car. I haven’t had any issues thus far. 30k miles on it.

[@fse7794]

K&N is too expensive, I found cheaper one for £10

[@MrTaodai]

how frequent do you change the air filter?

[@soc4me530]

I check it with every oil change and see how it looks. Being that it’s a k&n it doesn’t need to be changed just cleaned and re oiled.
