I was able to find a SL55 intake for a steal of a deal yesterday, so i am having it shipped up to me this week. Should have it by Friday, then i just need to pick up some fresh filters for it and get that bad boy on my 32. I was looking at using some AEM dry charge filters... anyone ever used them before and have some input on there quality? I also am looking for some help with how to mount them to the stock locations for the 32 intake and have it look stock? I have seen some other posts but none of them had a lot of detail on the finished product, and some pictures of how you did the clips would be worth there weight in gold. Thanks in advance to anyone who can help me out.

Isn't the '55 intake going to be longer than the 32? And isn't it darn near the same design? What advantage are you expecting?

The sl55 intake is just a slight bit longer but uses 3 inch piping, the air boxes are about 30-40% larger, and the Y pipe is far bigger then the stock 32 set up. It has shown on the dyno to add almost as much HP as the needwings DCAI. From a older thread the used found when comparing them that it was only a 1-1.83 HP difference.

Ah, sounds like a good plan then! I think worse case scenario, the front 2 clips just wont be fastened to anything.

Well after some tight fits and a few hours of work the full Sl55 intake is on my 32. I feel like I definitely notice a difference in the higher rpms and the exhaust note changed for the better. The engine cover does not fit quite as it should, but i ordered a new cover that i will be modding to get a stock fit. the clip positions had to be moved forward about 2 inches and it clips in right were the stock setup had gone. the 55 system is MUCH larger then the stock system. i would say the tubes are about a inch to a inch and a half bigger then stock and the boxes are about 40% bigger. I added in some AEM dryflow fliters and so far so good. If anyone would like info on the set up or how to install, let me know. I have to give a huge thank you to Latemodel 21 for all the info he was able to pass on form his install of the 55 system. pictures will be posted soon.

I plan to keep the 32 system. if i am to ever sell the car it will be going back to 100% stock. I feel pretty confident saying that my 32 is one of the first 3 to come to the states. it has a delivery date of 2/8/2001 and only one was sent outside of Germany in January of 01 and only 5 were sent out of Germany in February 01 to the rest of the world. sooooo, i feel i need to retain the stock parts. I did just see a 32 intake set up on ebay. not sure n the price but i want to say less then $300. I can try and find the link if you like.

These are the instructions i used

Removing the stock boxes-
I think that you will get the most useful info by looking closely at the "55" intake that is un-installed.
notice
the 2 spring clips on the underside of each air box
the nipple (for the crank vent) on the rubber coupler (between drivers side air box and y-pipe)
the 2 release fingers on the y-pipe.

begin by lifting the airboxes enough to dis-engage the spring clips (start at front) ... the air tube(s) (going from air box to radiator surround) can be separated from the air box as it is lifted.

next, dis-engage the crank vent hose from the underside of the rubber coupler

now, dis-engage the y-pipe from the throttle body (manually release both fingers on the y-pipe at the same time a s you do this.

Putting in sl55 intake-
In order to make the air boxes fit properly (and securely) you need to off-set the mounting clips AND remove some small amounts of material from each air box .

use either 1/8" or 1/10" aluminum to make the off-set brackets and then secured them with 3/16" pop revets. See pics for off-set dimensions and orientation(s)

The air boxes needed to have reliefs added (used a dremel with a 1/2" sanding drum IIRC) to clear some details on the upper intake plenums. And, some material had to be removed from one of the airboxes near the oil filler cap

you will likely also want to reshape the heat shielding next to the new airbox (passenger side). see blue tape in attached photo

you can use the SLK32 (C32) front cover with light modification, but I don't recommend it as it gets in the way of regular inspection of the SC pulley.

the "55" air tubes are (much) larger. to install them, you need to remove the air-guides on either side of the radiator. ADDITIONALY, I seam to recall that one of the tubes (drivers side?) was still to big (to pass through the opening even with the air guide removed), so it had to have a slice added (from tip back to engine side of radiator support) so that the tube could be slightly collapsed to fit through.

Where did you find all that history on the car?

Well, I started with the Data card that I received when I joined and checked that against the MB Vin decoder. That info gave me the 2/8/2001 Delivery date for the car. then I managed to find a official MB R170 SLK 32 run numbers which i will attach to this. That info showed that only one SLK 32 was sent out of Germany IN January of 01 and only five in February of 01. So with a delivery date so early in the month I am assuming that it would be in the first 3 to come over to the US and at most the 6th to come to the US. in the chart the numbers inside () are the cars kept in Germany.
