Where can you get the 12 hole injectors?

If I remember right the dodge neons with the rt trim came with injectors that are plug and play with the 4.0. Don't quote me on it, but think the dodge avengers too, do some extra looking around, find some at a self service part store, clean em and you should be good, or you can go the expensive route and just buy brand new from k suspension.

I bought 4 hole injectors when I did my build and I am super happy with the performance. I bought them from a guy on here, jhc7399, and he is super knowledgeable about them. He refurbishes three different 4 hole injectors. He has found the 12 hole are not very reliable so thats all he sells

Thanks to all. Between 1-4-12 hole, flow rate and plug type, I'm starting to grasp the concept. Probably going with some 12 hole 24#ers. to start...

I've come to learn that not all ebay vendors are equal. You cant trust the reviews much either. But it is a buyers marketplace and returns are generally easy.

That being said I'm running a set of ebay 12 holes on an 01 XJ and they perform just as they should with acceptable fuel trims.

Thanks for the info. Have you ever heard that the 12 hole spray too wide for the inlet causing some long term problems?

I have not had any issues with mine that I can quantify. It gets stock rated mileage and seems to have good power.
