Hi There,

Since the C180CGI engine layout is different from the C300, I've decided to post some easy to follow guides for those whom wanted to replace the standard Mann Paper Filter with a K&N High Flow.

Step 1 - Switch off engine and open bonnet... duh


Step 2 - Look for the Air Intake and Filter Compartment (Withe the Hexagonal Sticker)


Step 3 - Remove the top engine cover. No special tools required.. just lift up with gentle force.


Extra - Since we only have one air flow intake, the other side is blanked out.
If you need the part number for the blank piece for whatever reason, let me know. (if the picture is not clear)


Step 4 - Get your tools out. Namely a T25 Torx Screwdriver


Step 5 - Get your K&N Filter Ready. (We only need one and the part number is 33-2965)

Step 6 - Identify the 3 screws holding the filter bay and hose clip. The first one is beside the hose clip.


Step 7 - The other 2 are at the back, closer to the passenger side.


Step 8 - Swing filter open and lift up. Fit with the K&N Air Filter. As you can see the bottom part are just hinges that hold the filter bay closed.


K&N Filter close up


Manufacturing date stamped on the filter cover


Filter Bay Part number incase you "lost" yours

Step 9 - Showing some sand deposits in my filter bay


Close up of the sand deposit


Use a vacuum cleaner to clean the sand away


Step 10 - Replace the air filter and work backwards to close everything up.
The engine cover is held by four rubber pods shown here.


And that's all folks.

Good work.
Thanks for sharing.

Is there any improvement in performance by replacing the K&N filter?

Kaewen

I haven't ran it on the dyno yet, nor have I pushed the car too hard as it's still new with less than 1000km.
But I do feel the engine is lighter and more responsive.

The filter demands impregnation or he dry?

Davinong

thanks so much for sharing!! ive the e250cgi version of your engine and it looks exactly the same, i can finally change my stock to k&n

ps. looking forward if you decide to get the racechip, im very tempted as well haha

You don't really need to remove the engine cover to replace the filter, it may make things easier but it's possible to work the filter out without removing the cover, I did it at my last service interval. Great DIY btw.

Kaewen

true, but i find that removing the engine cover makes taking the filter box out a lot easier... (either that or i got big hands) hehehehe

stay tuned for my quad exhaust mod with the OEM C63 diffuser. Got the past yesterday and appointment schedule for Wednesday to get it done!

The RaceChip is on its way from Germany too. Once i get that sorted out, will post some comments here

Knightmare69

Pls document your install of the diffuser and quad exhaust, I looked under my gf's C200 and on the other side where normally where the other muffler would be on C300's+ there's actually some sort of cover/box. I tapped it and it seems solid as if it's actually a use for something so I'd be much interested to see what you find when you do yours.

Also, what chip are you getting? I'm leaning towards the TMC Motorsports tuning box as it's a more financially viable option compared to the big names.

Kaewen

Yup, on the box, but if you remove the 2 screws, it's actually blank. You gotta get some heat diffusers for the paneling. I'll post up model numbers and pricing soon. But just to show you what i mean, here is a snapshot of it.

Shoot... i've not yet uploaded those pics into my mac, but here are pictures of the heat panelling. All 3 of them cost less than USD150 total from the dealership.







This is what it will look like with the Black panel removed

Knightmare69

Interesting, I considered going this route but I think instead I'm going to opt for a modified muffler fit in the stock location. I just wish someone offered a better diffuser for ppl like me who prefer to stay single outlet instead of dual. Good luck and I look forward to your progress.

Distalero

The "engine is lighter"? What does that mean.

Kaewen

it feels more responsive and ready to rev...

Kaewen

to the guys who are waiting for my quad exhaust mod and review on the Racehip, sorry to inform you that you might have to wait a few more weeks.

An SUV ramped into the back of my car and now the boot won't close, and the rear bumper is wrecked... Just when i have all the parts ready for installation, this happens.. oh well...

Knightmare69

Sorry to hear, but this may be a blessing in disguise. Insurance should be able to cover the costs of the dual exhaust swap as well as the repairs no?

Petje

****, sorry to hear! Hope you are ok, thats the most important thing. The car is just a car.

Distalero

Well "feeling" aside, to really do this right you'd have to do before and after dyno pulls (same day, same fuel maps, etc), to see if the rev range has shifted (not a function of air flow directly, in my experience). Hard to believe in this age of scrupulous computer assisted engineering that MB would somehow feel it was necessary to plug the system up on the intake end, yet design the rest of a system that somehow responds to opening that intake; the days of pre-EPA emissions focus/pre ECUs are long over.

Davinong

Ouch, sorry to hear that. i hope at least insurance/the guy who hit you is paying for it.

Royce118

Ouch sorry to hear that man. Where did the accident happen?

Kaewen

hi guys! just got back from a long week in Bali.
My car's done up now and i can hardly tell where the bump was.

ooo and the exhaust and diffuser are up too.
I'll post more info when i had time to catch up with my work and recover.

meanwhile, here are 2 shots from the phone..

Petje

Looks nice, they look exactly the same as my Vath !

Also installed the racechip?

tanktube67

Looks nice.

Trek1200

Exhaust looks fantastic! Was this a custom job or is there a company doing a quad exhaust setup for the 180cgi?
