Re: Looking for 4 hole Injectors for '92 4.9L

Right. I was looking for 14lb, 4 Hole injectors that could be replaced as stock. I'm not really wanting to seriously modify my vehicle. I'd just like to improve on it with newer technology that's better than original and might provide some benefits. No matter how minor it may be.
