Intended to replace the stock 35 lb/hr "Brown Top" injectors found in 85.5-88 2.3 Turbo powered Ford, Mercury, and Merkur vehicles running factory Ford ECU's. The stock injectors have an issue where the plastic top delaminates internally which causes them to leak externally and isn't reparable. If your injectors and lower intake manifold is covered in a layer of grime, this is the likely culprit. If yours haven't yet developed that problem, they are still 35+ years old with hundreds of thousands of miles on them which makes it highly likely they are dirty and not performing the same as they did when new. This causes uneven flow cylinder to cylinder which is a leading cause of a blown headgasket or melted piston. Replacing a single stock injector will not resolve this problem so it's highly suggested that they are all replaced.
This listing is for a full set of 4 injectors.
Fuel Injector Features:
- Fuel Injector Spray Angle, Pattern, and Fuel Volume per millisecond meet or exceed OEM specifications
- Injector Nozzles designed for optimum fuel atomization (mist) for increased performance and fuel economy
- Rapid-Pulse Technology ensures proper fuel delivery at all RPM ranges
- Robotic Build Technology allows for consistent build quality and specification balance
Tech Tip: If an injector is old or faulty on a vehicle with high mileage, the remaining injectors are likely in a similar condition. Replace all of your injectors together to ensure each cylinder is receiving the same amount of fuel for better performance, less chance of engine damage, and improved fuel economy.

- 85.5-88 Ford Thunderbird Turbo Coupe
- 85.5-88 Mercury Cougar XR-7
- 85-89 Merkur XR4Ti
- Other 2.3T applications running ECU calibrated for 35lb/hr injectors (like earlier cars with an 87-88 TC ECU swap).
The ECU dictates whether you must run low or high impedance injectors. Stock 2.3 Turbo ECU's require low impedance injectors. Our PIMPx can run either high impedance or low impedance (4 cyl only). Our PiMPxs, PiMPxshift, and Microsquirt requires High Impedance. We are a big fan of the High Impedance Siemens units with our ECU's and suggest you don't run these 35 lb/hr injectors with any of our PiMP ECU's and since these are low impedance, they can't under any circumstances be used with our Microsquirt ECU's.
These can't be used to replace the 83-85 "Green Top" 30 lb/hr injectors UNLESS you're also upgrading to "large injector" ECU from 87-88 Turbo Coupe, 85.5-86 SVO, etc.
Add our Kirban 3-bolt adjustable fuel pressure regulator if you want to raise fuel pressure to squeeze some more power potential out of these injectors.
