SL55/63/65/R230 AMG: Renntech R230 M275 airbox air filter size
Below is the part number on both BMC's and RENNtech's website.
What's interesting is the comment on RENNtech's site that the BMC filter set doesn't fit their intake, which is unusual given that other RENNtech intakes use the factory sizes for their filters.
Do you have photos of your airbox and the Green Filters that are currently on it? Curious to see if it's an obvious different size / style.

Renntech airbox with old
You can see that the edges of the new filter on the left is a bit thicker then the old one on the right making it not seat correctly.

Where in NJ are you? I have a set of M275 BMC filters in storage that you're welcome to test-fit.
Separate note, there's also a good group of R230 guys in the NY / NJ area. We're going to try to coordinate more meet-ups and driving events this upcoming spring if you're interested.
