Re: Problems after 12 hole injection upgrade

because they were designed for 4 valve heads, and instead of spraying fuel directly into the intake port, they spray it off to the sides (where two smaller intake valves would be) and make a mess.

or so i've heard. haven't wasted the money to test a set.

I tracked the injectors down ignoring the ksuspension website all together. They are Bosch and the specs are only slightly different than oem aside from how the fuel is atomized with 12 holes vs single hole.

The specs are as followed:
43.5psi
22.8lb/hr
12 ohm


So im not entirely sure why they caused a miss at idle and bucking under load since 96+ used 49 psi and 21 lb/hr. Am I missing something here? Slapped the oem ones back in and it doesnt buck or miss at idle.

Those are going to flow 24.2 lbs/hr at 49psi. I'd wonder if they genuine Bosch, or fake chinese knockoffs that seem to be flooding eBay? Do they have an actual part number embossed in them? https://www.injectorsonline.com/us/b...ors-and-pumps/

Re: Problems after 12 hole injection upgrade

K-suspension is peddling Chinese knock off injectors, I posted screenshots and proof. But the CLUBXJ kids laughed it off and said "but he has good customer service."

Re: Problems after 12 hole injection upgrade

I recently installed genuine 12 holes and see little difference if any. my mpg has stayed the same and i'm hitting 12-14 around town which is normal, slight exhaust leak from header crack at collector. highway i can pull 20mpg all day. i think they're a waste of money for this engine.

Re: Problems after 12 hole injection upgrade

so after all this -- would it be smart to just have your stock injectors cleaned and rebuilt?

Here's a picture of his injectors from this site. Notice how deep the bosch logo is stamped into the injector body?

https://www.ksuspensionfab.com/store...Injectors.html



Notice how shallow the bosh logo is on the genuine injector?



Same with this other genuine injector. You can also see how much cleaner the casting is.

I think this thread says it all. You really should go back and read it again, you were told several times about those injectors.

I was told they wouldnt work. This is about WHY they wouldnt work. If he is truly ripping people off then let's get to the bottom of it.

That or buy directly from companies such as Bosch or a dealer. Which is what I'll likely do in time. I'm not in a rush to upgrade from stock

Problems after 12 hole injection upgrade

This is also more strangeness. When the first set didnt work I was sent a second set. I now have 2 sets. Both are different colors and have a different spray pattern. I'll post pics
