What are the stock injectors on a 1999 GT. My car has 78,000 miles, and I am thinking of just buying new ones that match the factory ones. I just want to make sure that I have good fuel flow before I start upgrading. I dont want to do the recalibrated MAF, just replace the stockers

 

The stock ones are 19.

 

There is no need to replace them if the car is running fine. With 78k they should be ok still.

 

No need to replace inmjectors with like size.

You can have them flow tested if you want for about $100

 

Yours are fine, if they werent then the car would throw codes and youd notice.
