Worked well

Finally got around to changing out my old 2 hole injectors for these new 4 hole injectors on my 5. 3 L33. Pretty easy to change out. I pulled the intake off and did it on the bench to make it easier. Performance wise I noticed better idling and more throttle response. I am happy with the purchase.
