Kidney grill question
I just replaced my silver kidney grills with black ones. When I took my old ones out there was a rubber inner grill to direct air right into the turbos. When I switched to my other grills I could not figure out how to put the inner rubber part back on. So my question is how important is it to have these rubber fitting on for the air flow? Attached is a picture of the rubber fitting I am talking about.
Thanks in advance,
John
