Does anyone know how to replace the air filters on the current G63? I can't find instructions online or a service manual.

I have two K&N air filters sitting in my garage and I'd like to install them.

Any help would be appreciated.

 

I’ve heard from multiple sources the oil from the K&N filters can make its way into the turbos causing issues.

Might want to hear from others

 

New K&N filters won’t cause any problems. I cleaned and over-oiled a set and it fouled the mass air sensor, easy to clean though.

 

Absolutely senseless - "K&N air filter" for your W464 AMG G63 - grow-the-frack-up... it's AMG's best and you might think that AMG might know a "bit more" about filtration/airflow than the "High End Air Filter Brand at O'Reilly Auto Parts"... gee'z..

 

Of course Mercedes always knows best....like putting 22" summer street tires on a four wheel drive wagon with three locking diffs. When I wanted to put a decent set of all terrain tires on my G63 I had to buy a set of 20" take-offs from a tire shop.

I asked a simple question and you turned it into an attack.....yet you tell me to "grow-the-frack-up". Is that a Battle Star Galactica referrence????

 

lol... whats with the attack. i've used oiled filters on a lot of my cars even though i havent bought a set of for my G. you can keep cleaning them and reusing them. so over the long term, you save a bunch of money.

 

ouch😳

I just put a set of K&N filters in my G63. Nothing wrong with helping the engine breathe a little easier, and saving money by reusing them. Just oil lightly. 🤷🏻‍♂️

 

I've used them on past vehicles and never had problems.

 

Most Important - Ignore fabbrisd1!! For some reason he thinks he is the undisputed authority on everything. He is entitled to his opinionbut so are we.

INSTALLING THE K&N FILTERS

Be assured as with many things, the first time is a true “learning experience”

1. After you open the hood on a cool motor, be sure to take a minute or two to identify where everything is and get your tools ready.

2. Clear off a padded area to put your engine cover on so it isn’t damaged.

3. Cover both fenders and the front area above the radiator with non scratchable padded material.

4. Please understand that MB uses those rubber press connectors on alot of areas. If you aren’t familiar with them and how they come off and on, try a R&R on a test connection.

5. Removing the engine cover - Gently reach under the cover in the front and apply upward pressure to just release it in the front not take it off. Then work your fingers toward the rear of the engine on the drivers side (left side) until you feel a long support piece that is attached to the cover and press fit in a receiving area at the top of the engine. Again gently apply upward pressure until it releases from the engine side. Now move to the right side rear and you’ll see where it is attached. Remove it and set it on your padded work bench.

6. Air Boxes - Now you can clearly see and have access to the air boxes. First using a screw driver or small ratchet, loosen the hose clamp closest to the air box taking note of where the tightened clamp is positioned so you can put it back in the same place. Then loosen the clamp on the other end of the hose so it can be moved with your hands. Loosen and remove just the end of the hose connected to the air box. and move it out of the way of the opening hole.

Now locate the 4 torx type screws that hold the front of the air box together. 2 on top and 2 on the bottom. Remove these screws and set them aside. You may have to locate the rubber press fit connectors on the air box and gently lift up on them to raise the airbox up enough to remove and install the filters. ALSO, please be sure to locate and become familar with the connectors that are attached to the air box. You don’t want to break any connectors or wires. Also be sure to recheck these connections when you reassemble everything.

Air Filter Installation - Before removing anything, be sure to study the direction of each stock filter in the air box. Also, there is a finer filter attached to the stock units that you won’t reuse since the K&N’s are one piece. You should be able to lift the air box up and remove the stock filter and install the K&N making sure the filter seal in the air box is not pinched or out of position. Then replace the airbox screws, check the connectors, place the airbox over the rubber connectors and gently but firmly press downward until it is secure. Now, replace the hose and properly align and tighten the clamps. CHECK YOUR WORK. Then move on to the next one which will go much faster. Retest all of the push connectors. Now replace the engine cover taking care to secure the stud/connector first and then the right rear and finally the front ones.

FIRE IT UP AND ENJOY.

My own experience is that it has more seat of the pants power through all of the ranges, it seems to have a deeper exhaust tone with more air moving through.

I think it is well worth the money and time spent.

Please let me know your thoughts.

Best regards

Jerry

 

A K&N rep mentioned to me that they provide a 1 to 1-1/2 percent hp bump. I didn’t ask him about a cold air intake but assume it would be a bit more.

 

Thank you Sir, I appreciate the help.

 

Ok, so I finally find the time to go change the air filters and get one side open only to realize I have the wrong filters. I placed an order for the correct ones and now I have a pair of K&N 33-3072 filters that I can't use. I ordered them months ago so returning them probably isn't an option.

If anyone can use them let me know....no charge.

 

I'll take them if you are offering...I just sent you a PM - thanks!

 

Daniel:
You want the SKU: 33-3140

I recommend you call and ask if they will accept your current ones back in exchange. I have always had good experiences with them over the years. Just be sure the packaging is still like new.

All they can do is say NO.

Best regards

Just installed the K&N filters in my 20’ G550

Saw this video from reputable YouTuber with engineering background scientifically proving a real world 2-3% increase in HP/Tq and 0-60 time.

I would add to the instructions above:

For the engine cover there are a total of 6 press-fit attachments (3 along each side, left and right) that hold the cover in place. They come up fairly easy.

Once cover is off I would loosen large silver ring clamp around the largest hose that is located medially to the airbox first with a flat head screw driver.

Second loosen small black rubber hose feeding The airbox from the front with a pair of heavy pliers. This clamp is tuff. Will need heavy pliers. Hose dose not need to come off, only slip back off of airbox enough to provide slack.

Then with a size 25 torx wrench unscrew 4 screws. All located facing upward on the box. Loosen until they spin freely. Should not come out entirely.

Then pull up gently on the airbox lid from the front. (Caution not to disconnect/displace the electrical connections located at the rear of the airbox.) Two press-fit attachments should come loose in consecutive order. This allows the front of the box to come up enough to slide out the paper air filter (I did it in pieces as it tore with little resistance) and slide in the K&N filter. The K&N filter slides in much more easily as it is thinner than the original paper one.

Will report back with my driving experience.

 

Success - thanks for the instructions and especially Daniel for the filters! No issues but as stated removing the hoses in front (and putting them back on) is a *****. I used a pair of channel locks but they are stiff, hard rubber that does not want to move much. I'll see if I notice any difference in sound the next time she goes out.

 

Does anyone have pictures to where these 4 torx screws are. I have been able to get the engine cover off on my 2014 G 63, but i cant find teh screw.

Thanks

 

The screws are on the bottom of the air boxes. Remove the air boxes and flip them over.

Photo shows driver's side (passenger side is mirror image). Torx fasteners are located where red arrows point and are T25.
NIce to know that others are doing this kind of work for themselves.

 

Gotcha. So no screws from the top. I am struggling to get the air boxes out. Even after I have taken the engine cover off..They just seem so solidly stuck that I thought maybe there are screws holding them down. Maybe yank a bit harder , I guess. Thanks

 

My air box is different. Let me go home and post a picture. Thanks for the help though.

 

here is how my engine looks- so I need to remove hoses and the air boxes will pop out??

 

Sorry - my reply was directed to the OP. I didn't catch the MY "2014" in your question. If you know your engine model number, check to find its use in other MB car models. If you can't find a shop manual for your 2014 G, you might find one for another car model with this engine.

 

each item is numbered.

1-remove the 3 covers by pulling each cover up gently
2- loosen the hose clamps, 4 total
3- separate the sensor connectors, one on the back of the driver side air box, and one on the side of the passenger air box. There is a small tab/lock that keeps the sensors together.

then pull the air box up and out of the air intake piping. Flip over and see the torx screws to open the air box.

 

this was very helpful. I followed these instructions and was able to get my air filters switched. Thanks for helping out .
