I recently purchased a 2016 SLK 300 with a 2.0L 4 turbo. I originally purchased it as a semi daily driver for my wife to replace her G37 that I sold. I fell in love with the car and would like to do some performance upgrades. Being as I am new to the MB world I have no experience with these vehicles. Are there any upgrades for this 4cylinder turbo? Hi flow filters, cold air intakes, pulley changes etc. yes I realize that a 4 turbo may not be the best “performance” engine to start with. Are upgrades available? Is it even worth the time,effort and money on the 4 cylinder?
If you want more speed i have used RaceChip they are very good with their customer service response German i think and been around for quite some time.for louder exhaust i had the 2 back boxes chopped off my SLK 200,although i stored them both and can have them welded back on any time i wish,IMO just yesterday i posted on a thread that although i would love a 6 pot or 8 pot engine if i was to buy another SLK/SLC your SLC 300 is the one i would go for based on reviews i read and watched,i believe yours has exhaust enhancement of some kind in sport+ is it?and around 250bhp?
RaceChip Pro 2 i had on my 18L 200 easy gave me the power of the SLK 250 petrol which is around 200bhp i think my 200 is around 184bhp stock!
When i had the back boxes deleted they sawed them off let me listen and offer to weld them straight back on if i was not happy for about Ł40 i had mine chopped over a year ago now and it passed MOT fine.
You can control the volume of the exhaust with your right foot
i left them off and cost was around Ł140 i think as they have to weld the chrome tips back on but does the SLC have fake tips not connected to the pipes now?
But i think your SLC may have some kind of opening valve in sport+ and if so i think the 4 cylinders needed a more sporty sound at lower revs but i never lost that blurp sound i do like when gear up changes happen at higher revs!
UPDATE this video explains more about the SLC 300 i was talking about ie the exhaust valve and fake tips!
