Fuel injectors


Recommended Posts

I know this topic has been done before but What is the difference between the 5.0 injectors verses the neon injectors as an upgrade? I know both have 4 ports instead of 1 (did a stratus injector upgrade on my XJ and it seemed to make a difference to me) but are they both plug and play? Is there a fuel economy difference? I'm assuming that they both will make it idle better but I'm not sure.

If you are running the Renix motor, go with 746 injectors which came in the mid-90's Volvo 850.  They have a 4 hole spray pattern like the 703 or the 710 but are the same poundage as the stock Renix injectors (I believe 19 #).

The Ford 710's are 19# as well as the Neon 703's.  The Volvo 746's are a good choice too, but the nice thing about the 710's/703's are the one piece design.  They can't leak at the mid section like the stock and Volvo injectors could.  Google "Jeep fuel injector upgrade" and I guarantee you'll find a ton of info on various forums.  That should give you a good indication of what will suit your needs and give you years of which vehicles to look at.  I can't remember which years I got what from...

I'm not 100% sure but aren't the 703/710's a different plug than the stock injectors? 

 

Like Bobolink said the 746's I have are 1 piece and the plug is the same as OEM.  Check ebay - I got 6 shipped for $35 this past spring (cleaned & tested) then spent another $25 or so on new o-rings.

703's and 710's are the same style plug.  Also, I was mistaken on the 746's... I was looking at my dad's Volvo (which I assumed had 746's) and his are the fat-bodied, two-piece design.
