Air filter for 07 TSX is 17720-RBB-A00 (Blue). What, if any, is the significance of the "Blue"? Wix lists their 46831 for this car. It is quite white! Thanks.

Color doesn't matter. Toyota Prius air filters were yellow and now there white. It all depends on who they get to make the filters. Its just an air filter no difference.

Thanks, that's what I figured although there must be a reason Acura goes to the trouble of adding "Blue" to the part number. It must have something to do with part identification, supplier designation or inventory control.

That's exactly what it is. If there switching suppliers they will have (blue) until they run out of them or until the old ones runs out.
