M60 540i Injector Replacements

Well, it's been two weeks since my injectors were shipped from the refurb shop by USPS and they still haven't appeared. This will be the frist time I will have ever lost a package by USPS.

Preparing fo the eventuality of having to replace the set, I checked out FiveO Motorsports and saw they had two different applications for a 540i V8, a new design 19 lb OEM replacement, or a 'green' 20 lb injector. The only 'mod' on my 540i is an EAT chip.

Would it be worth the $10 price differential for the 'green' set?

With my luck, they USPS will deliver the 'lost' package the day I install.

Thanks!
