This should have it good to go. For reference, I am going with Bosch stock remans to the tune of about $2400 installed.
Maybe, maybe not. Remans are not a sure thing.
In the overall scheme of things NEW stock injectors are not that much more if you shop for deals.
If saving $600 is a financial make or break then you do what you have to do, but, ONLY if it is a critical juncture.
