What is the difference between US grills and Euro grills?

[LINUS]

Is it true that the only the evo3 had the oem black plastic kidneys?

I don't think any of them came factory black - the chrome kidneys are almost as trademark as the prop on the emblem.
I see a few Sport Evo's on S14, and they all wear chrome.

Thats what I thought.

According to RealOEM the kidney above is used on E30s with A/C. Who knows...From my observation, US E30s had the fully opened kidneys and Euro Spec E30s had the partially closed kidneys.

I order and recently put on some euro grills and kidney.

Is there really a euro kidney? I saw one on the ebay and told the lady that she had one because this was the same as I had recieved with my euro grills.

She said that her husband of 25 years working on BMWs says that the below picture is not euro. I don't really care but I thought it was. She said that on the open kidney was for the non front spoilered cars and the insert one (below) was one's with front spoilers

True or False? I really have no clue now. I just emailed her back and was like well I guess everyone on the forums are wrong, I guess I won't listen to anything else you all say....haha

Yes-
Those are the correct part numbers.

so are you saying the kidney with the plastic piece has better cd and makes a noticable difference to how it performs???

If this is true. put me down for 21 of them.

The cd is a way of looking at how easily the car move through the air.

I doubt having the top inch and a half blocked off is going to effect much.

Some say that it is blocked off to allow for more air to the radiator. It might accually provide less air though. It's hard to tell.
I'd just use which ever one is in better condition.

I think a lot of it was BMW seeking to lower cd as much as possible without redesigning the car. I know they were roundly criticized because the Audis of the day had amazingly low cd numbers. It also would've made incremental improvements to the car's top end.

is there any advantage to having one partially blocked off as opposed to not blocked off at all??
