  • Designed in-house using state of the art 3D laser scanning and CAD technology for precision fitment 

  • Overlays the factory valance to provide aggressive rear diffuser styling 
  • Outer blades are designed around the OE blade surfaces and made more aggressive by lengthening and tapering the blade towards the bottom

  • Center blades fill the empty cavity of the OE valance and feature countered upper mating surfaces to the OE valance for a seamless fit
  • The bottom of the valance has provisions for mounting to the OE body brackets

  • Sheet metal brackets are used to mount to the bottom of the OE diffuser using stainless steel hardware and rubber insulated well nuts

  • Textured matte black finish resembles the OE valance texture for OE+ appearance 

  • Manufactured from ABS vacuum formed plastic with UV additives to stand up to the abuse from the elements

Very tight fit on 74mm Mobile 1 Filters
Color: Silver
It claims to fit "some" 74mm Mobil 1 filters. It's a fraction too small, but will work if you "force" the tool on the filter.

It’s Mobile One. The Brand Says it All!
Size: 5 Quart (Pack of 2), Style: Full Synthetic, Configuration: 0W-40
I buy Mobil One 0W-40 Full Synthetic European Blend Motor oil for my three older, higher mileage Mercedes SUVs. Considering all the vehicles are running well to this day speaks to the quality of their ongoing maintenance and Mobil One lubricants have always been part of their routine. Mobil One long ago became the favored brand of both European luxury car manufacturers and their customers. I’m no exception. The product comes in a convenient handled bottle that’s easy to pour without drips or spills. It’s built in fluid level gauge provides you with a real time window into the quantity of oil you pour and quantity remaining in its container. The oil is an excellent lubricant and it’s great for my motor, too. Price wise, it’s a premium offering from a premium brand. Even so, it’s worth every penny for helping keep my vehicles running as they were engineered. I have no complaints with Mobile One and I don’t have a reason to change. I’ll keep buying it until something better comes along.

Mercedes certified - this oil is very nice, no need to drop loads on oil from MB or the other pricier brands, this stuff works very well.

Works great never had a problem
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
I've been using this mobile one in my 2005 Mercedes kompressor C230 w203 1.8 engine for about 18 years and never had a problem so I will continue to use it. The price was very good compared to other places but I did have to order one extra quart, I don't know why they don't make this mobile one in a six quart jug.
