Good that there are other intake options now but Dinan makes the best intake for this vehicle..
I know this forum is infested with Dinan haters but their fit and finish on par with BMW standards and more important than everything else;
No CEL light! Which will guarantee happen with any open intake due to the sensitive MAF sensor mapping.
When the MAF senses an abundance of air as with an open intake, which is not inline with the factory parameters, it sets off a "plausibility" error code.
