Ok ,I heard this just yesterday that all Mercedes air intake engine covers on V-8s since 03 fit on our car ! They have larger intake pipes and filter boxes ,larger filters to let enough air in for the V-8s.
I'm going to try this simple mod to see how it might effect our V-6s .
Also i was told that MBenz uses this same box on most of their V-6 cars other than the old SLK.

 

Go and grab some at the backdoor.You're closer. I haven't got it yet,next week.

 

If possible (assuming the v-8 intake fits) try to get 0-60 times before and after, preferably using some sort of accelerometer like the G-Timer.

 

The V8 air boxes will not fit. There is not enough room in the engine compartment. What will fit is the SL55 Y-Pipe that connects the stock airboxes to the TB. A little modification is needed but it will work without too much trouble.

 

I have been told by a XFire owner that has confirmed they fit .But I will keep this thread up to date if I confirm otherwise.

 

It's a real car not like the LOTOY but built in the early Fifties only 3 wheels and US built.

 

There was one at this show too.Almost completly restored !

 

The reason why the box fits is because, the 6, & the 8 use the same block. What I mean is that both the V6, & V8 are cut from the same cloth. Just one is poted to be an 8 cyl and the other for a 6. If you look on the engine it self, you'll notice a lot of open holes, with no screws in them. Thats that way for two reasons. One is for diff. comp. for the SLK32, and the Second is for added Comp. for an 8cyl motor. If you look at the coil packs on the engine block towards the firewall. You'll see ther is actually an open spot for a fourth coil pack, on both sides. I thought that was kind of a smart play on mecedes's behalf. Hell you'll save a boat load of money doing it that way.

 

I'll take your word on it because you had your head under a Crossfire hood probably more than a DC mechanic.,,,,,He, my freind said a simuliar reason ,saves them $$.

 

You are wrong. The boxes do not fit. It has nothing to do with the engine block and everything to do with the room in the engine compartment. If the engine compartment were larger you would not have a problem. As it is there are items under the hood that are in the way. The same issue applies in looking at the SuperSprint headers designed for the MB V6 engines. They will not work on the Crossfire or SLK due to stuff in the way.

 

I never said the chasis on the V8 wasn't bigger. I'm simple talking about the block it self. The engine bay's on all the SLK series Mercedes are all pretty much the same as far as setup goes. As far as size goes, just look at the car. Is the 55 bigger then the 32? I'm thinking.....Yup.

 

srt 6 roadster i hate to burst your bubble, but YOU! ARE! WRONG! I HAVE THE AIRBOX THAT DAN-ROOT IS REFURRING TO, AND IT DOES FIT & AND THE HOOD CLOSES, WITHOUT A PROBLEM. LIKE SASKIN SAID ITS THE SAME ENGINE LESS 2 CYLINDERS!!!! AND YES I WILL UPLOAD PHOTOS TO MY GALLERY, TO BACK THIS UP!

 

Thanks babeviper ,I been waiting to see you here.call me or I'll try you today.was that cover off a 5liter or does it matter ?and the year was 03 ?and up right.

 

Dude, no need to yell (post in all caps.)

Post your photos of the airboxes fitting in your engine compartment. I know people that that have tried and they would not fit properly. I will look for the photo's that show the airboxes not fitting.

And again the problem is not the engine but the engine compartment.

 

hi folk,s sorry about the thread posted in capps, it was 3am and i was tired.the post was not ment to be a war , i simply wanted to show that the air box does fit , and the only fitment issue,s are the air tube,s they are larger, then the ones on the crossfire. other than that the box works fine. I do not endorse any benefits that are to acheived from the box, save for the fact that the air boxes are larger and the filters are bigger, and the air tubes are bigger in size, other than that i do not have any hard evidence of any performance gain,s.

 

If the V-8 boxes I would guess they are worth ~5hp stock and ~8-10hp if running additional boost. Let me know when you get the pictures up I am interested to see if you got them to fit and look right.

 

Saskins, I swear you take stupid to an new all time level. Blocks are not ported to add cylinders. They are cast. They are cast as a unit with the holes for the cylinders in them. The 6 and 8 are NOT the same block. The additional holes are on virtually all engines and are for additional options, not to add cylinders. I really wish you had a clue as to what you are talking about, because you sound like a complete idiot.

 

srt-6 roadster, hey bud the pictures have been up for 2 days now. and it seems to me that you don,t know these cars at all. theres only one air box for the car , and it sits on top of the engine, not one box off to the side. the pictures are in general section of this form. i think if you or the friends you know, really had crossfires or a mercedes you would know whats up on this matter.

 

Hobbyman,
Dude go **** yourself. What I was talking about is, the block from raw stock, the they used the same over all sized pieces of alum, when CNC machining them. They found a nice grey area with the size to be able to do what everthey want to it. Whether that be make 6, or make an 8, they could do both. This way they can save a **** load of money. Its actually a really good idea, for a major motor corporation to do. Its almost like killing two birds with one stone.
Hobbyman can I ask you a question, what does it feel like to wake up every morning and realizing that you can't stand who that guy is in the mirror. It must feel like absolute Sh**. Huh so I got an idea, lets not make "me"(you there cheif) lets make it about everyone else around me. That way when It will confirm that I am this rejected failure. I mean hey look at how everyone responds to me, it always negative......Hey hobbyman its time to grow up man, stop playing the game and step up to the plate and deal with what ever is angering you. Ex: If your father did, or did not do something to you, or with you. Address it. If Pops is still around, just reach out and touch someone. I think you'll be a much more happy person, instead of the miserable guy you have to live with.

 

Hobbymanbill, please go away! You're a cancer to this forum.
