Greddy injectors are one of the best I ever used and affordable. These are direct drop-in with no modifications what so ever.

I went through other injectors that had problems with. After purchasing these 660cc injectors from HPF, I was really satisfied with the qualitd and ease of installation. These work perfect with my setup, it was the last thing I needed to make 524RWHP SAE on my 7M. Thanks HPF.

These are LOW impedance injectors (about 3 ohms).
You may need to add a resistor pack or a 10 ohm 10 watt resistors to these injectors for high impedence applications.
Good quality product. I needed more fuel to support more boost. These were installed in my 89 RX-7 Turbo.
Be sure you have the proper o-rings, grommets and electrical connectors for these injectors. In my case, I used Mazda O-rings and grommets. The local parts store had the injector clips. It's a good idea to replace your fuel filter as well. If you replace any fuel lines, be sure to use "fuel injection" hose, not standard fuel line. Expect to pay about $1 per foot for this. The line must be stamped "fuel injection".
Again, no problems with the product, just be prepared to aquire the other required items.
Good Luck,
