OP, I know the Injector Dynamics injectors in the link are somewhat pricey... But I've seen WAYYY too many positive reviews on these. You may not want to pass up I.D. injectors.

 

DO NOT get the ones on Ebay,
they are made by VENOM...aka:Crappola.
My recommendation is to look at RC injectors,Greddy.Denso..ID's if you can afford them..anything BUT Venom,,they do not flow correctly.Period.

OMG niiiice!
i like those.
im gona order 2 for my secondaries.
thanks for sharing that.

 

+1, junk.

injecTORS not "ters"

 

it should be injectears.
Because with ebay injectors, the will inject tears into you when they are the reason to why your engine blew up. LOL ok that was cheesy

OP, go with Injector Dynamic if you can afford them, other wise, RC engineering or Greddy/denso. Though if you are buying brand new, ID injectors are only 30-40 more then RC engineering ones for a pair.

 

im gonna use my stock fuel rails . its an s4 i dont want todo no cutting or anything . were can i find the greddy denso ones?

 

Just give @turblown a call. Customer support is awesome. I think ID makes a plug and play adapter harness for the ID's?, and I know they make the tops for them so they "just fit" with no cutting or trimming required like some other injectors.

 

All the ones I mentioned are all drop ins.
They all fit into the factory rails with no modifications. WIth IDs, you must get the 14mm tops, the standard tops are 11mms.

I dont even think they make greddy/denso ones any more. RC uses the same style injectors as the Denso.

Also, when getting new injectors, you should also get new seat cusions for the injectors if they are cracking, or isnt making a tight fit. Mines was pretty loose and was a cause for one of my vacuum leaks.

 

i plan on it man . thanks . now for the injecter resitors does my year have them? its a 87

 

What I've read 87 should have a resistor pack below the air filter. That means you're run low impedance injectors and the resistor pack takes care of the rest.

Get out your ohm meter and check the injectors you have now.

 

the resistor is near the air filter area, it should look like this
