Injector Size/Upgrade

2966 Views 2 Replies 3 Participants Last post by  [email protected]
I have an early 99 and would like to upgrade the injectors. The stock injectors are Ford #: F61Z9VE527BRM

1.) How many cc are the stock injectors?
2.) Recommendations for largest size to upgrade

Thanks, I would appreciate your input.

Bigger injectors require supporting modifications. What are your mods currently?

Stock e99 injectors are 120cc

You can upgrade to late 99-03 injectors which are 140cc. Direct swap.

But you will still a chip to utilize the extra fuel. Which requires Intake, exhaust, And gauges.
