injector problems
 

well i took my car apart to start the lexus maf swap and when i got the injectors out i realized that my 550s didnt come with the rubber gromet that is on the bottom of the injector and 2 of mine are garbage, does anybody know where i can get these little things??
also when hooking up the injector clips both wires are white on the new ones does it matter which one goes to the red on the orginal wires?

thanks tyler

You can get the grommets from your dealer.

They aren't high $.
