Also got the recharge kit....didn't know if I needed to pre oil prior to install or something.

Thanks for the info.

The package will usually say if the filter was pre-oiled.. If it WAS:

If you can visibly see the oil on the filters and they are oily to the touch, I would leave them unwrapped on a table overnight to let them air dry a bit before you put them in.

If it WASN'T:

Add a uniform amount of oil to each line in the filter.. Just enough that it soaks evenly. Don't over oil it!

Wow, so basically these are like cotton K&N's? No offense to either side that is.....just thought these were super thin cotton filters without oil....weird.

Interested to see if I feel any difference.....I would imagine not as K&N are pretty free flowing (to the motors detriment some say) .....gonna try to dyno and see soon.....if I could just get the friggin time.

vrus

Yikes.. I better retract my comment above.. I am ASSUMING these are the same as K&N's but just more porous to allow more air through.

I also ASSUMED they were basically the same material and required the same care. I've personally not used them, but that is what I thought they were.

Better let someone with first hand experience chime in here...

I would be careful running these filters. Being that our cars are supercharged, the oil from the filter can actually come off the filter and get lodged on the Mass Air Flow sensor. If this happens, the MAF will go bad, which is not a good thing. The MAF is the primary load calculation for fueling and transmission shift points. All it takes is a MAF that has drifted out of calibration and a high-speed run to toast your engine.

2003 and up E55's are speed density they don't have a MAF.

No biggee V...you are mod MASTER.

Thanks for the input.

dragonAMG

Lucky for you... I guess I'm the only one that has to worry about that problem.

The filters do not need to be oiled unelss your clean them which should be at about 50k miles.

How do these filters compare to K&N's?

MB Fanatic

K&N are much much more porous, therefore, allowing more air to pass through them, as a result more dirt and dust passes through them.

The Green filters are made with a synthetic cotton fiber that filter just as well as stock filter, yet allow the air to flow more freely than a K&n filter. I should be getting mine sometime this week as well. I have been running stock filters this whole time and just changed them a few months back. I cant wait to see what the Green filters do.

I felt more of a response when I changed to green filters. You do not need to oil them, they come pre-oiled. They have ALOT less oil than K&N's which is why you can barely even tell they are oiled.

vrus

Someone do me a favour and post a pic of what these things look like. 1 shot which shows the whole filter and 1 shot which is a close up of the filter material as close as you can get it.

Please and thanks.

blackbenzz

vrus, I would take a pic of it but its in my car and I dont even have a camera with me. Looks exactly like K&N but less oil and of course, GREEN

Jakpro1

Here V...bout as close as I can get with this friggin 500$ piece of junk digital....grrrrrr.

My kids kodak gets closer.

vrus

Thanks for the pic!

Now, who was saying that the K&N was much more porous??? NO WAY!

I can see right through the filter and can make out the sidewalk in the first pic. You can't see through a K&N. Hell, I can't see through my BMC race filters either.

I think these green ones will give you more flow, but they are DEFINITELY more porous than a K&N filter. You can't see through the K&N when you hold it up to the light.

There is no way this thing will filter any better than a K&N. If anything I think it will make MORE POWER than the K&N BUT IT WILL FILTER LESS.

That's my $0.02....

blackbenzz

Thats where you're wrong vrus, they have magical GREEN powers and they can filter better and flow better than K&N

BMWEATR

looks like who ever makes the K&N's make those too?
I just inspected my K&N's and found the wire mesh comming apart so i had to pull them and put the stockers back in. everyone check your K&N's extremely close, I could barely see the little wire pieces comming off.

Beowulf

The QC on K&N's has apparently gone to hell in a basket. I'm a long-time user with numerous cars - never have had any probs until the E55 filters. I inspected mine carefully upon receipt and found a number of loose wire particles, which I removed piece by piece. I checked them again after a couple thousand miles and everything appeared to be okay.

I'm getting paranoid now - go back to stockers or switch to the green filters? I've never heard any negative feedback about the green filters performance. Any first-hand user input out there?

BMWEATR

thank god, i thought it was something i did w/ them that made them come apart! I'm sure glad i filled out the warranty paper work (didn't do it) $60 bucks down the drain!

MB Fanatic

Vrus, the Green's are not more porous than the K&N. What you are seeing is the sun reflecting off the filters cause of the slight oil. I just got mine today and I can assure you there are no holes in the cotton material. I will be installing them tonight, so I will let you all know how they feel on a stock E55.

Rafal

This is beginning to worry me guys!
I've used K&N for 12 years and never had any problems! My MBZ dealer installed these filters in the E55 and I told them to check carefully for any loose metal bits, but did they?
I just ordered the Green Filters from Neal, just in case! Fear is great for new business... remember the Y2K ?

Here are a few pictures i took before for anyone wanting to see what the Green Filters look like.

I took one up to the light with a flash, yes u can see threw it a bit, but thats is simply because they are a thin cotten. Just like if you hold a cotten t-shirt up to a light you see threw it. Thats the oils job to keep small particals out.

I also took a picture of the backside of the box showing it states the filters are pre-oiled.

Vetluver

Maybe I'm a little suspicious but they sure do look like green K and N's The construction is identical. I think I'm from Missouri on this one.

MBZAMG32

What's up guys!

Any one here that have heard or used the Blitz air filters for the 2002 C32 AMG. Which one is better K & N, Green filters or Blitz? And how much are the green filters for 02 C32 AMG?

thanks,
Robert
