Did you already install that? Unfortunately that KS is fake. If that's already on your car thank your lucky stars it hasn't FUBAR'd your car. Check out my experience with the fake eBay KS:

*edit* also - just think about it. How/why could somebody sell a part that costs $150 for less than a third of that? It makes absolutely no sense they could be genuine. Either way though glad it seemed to work out for ya but my experience with them was awful. It makes it worse for us because our knock sensors are so hard to get to. All the 4th gen guys it's no skin off their backs because its a 10 minute job for them. They're really good fakes physically but if you compare them and their packaging to the OEM ones you can spot the differences.

No, James not the same seller you dealt with; Car Parts 4 Less is the seller I bought it off. But genuine or not; I seem to have the same experience that the 4th & 5th gens have no issues after 1 week.

I got a new OEM o2 sensor last week for $30 shipped.. It's about $100 more from Nissan. But it's not some BIN where hundreds have been sold.

James is right about that being a fake. You can tell just from the label. Ink is way too dark and bold for that to be a real label.

On my VE. I didn't have any luck, just changing one, so I ended up changing all of them. If you want the document I had my mech. use, pm me. I have it in word format. If you're gonna change them all, you're also gonna need:

(1) knock-sensor harness 24079-96E00

(1) Knock Sensor 22060-30P00

(2) lower manifold gaskets

(1) Throttle body gasket

And some hi temp silicone gasket maker. For the coolant housing.

NOPI, has OEM quality injectors for our SE cars for $42 ea. by Python, AKA Venom (same company); there is a core exchange. The one's for the SE (DOHC) are not in the online catalog; you'll have to call Bobby. I just ordered (6), he said they're all new. Go figure.


NOPI
800-277-6674 - ask for Bobby Evans

Before replacing your suspect feul injectors you should really try putting this in your tank;

Costs pennies(relatively) no parts to open/remove. If this fails, then replace 'em.

You can use the TC-W3 stuff all the time. If you use it the 1st time and notice maybe a little difference, keep using it. It may slowly bring your injector back to life. Because the gumout is a cleanser only, it shouldn't be used regularly.

I use TC-W3 now and I have no injector issues, and my car has since gotten way quieter because of the TC-W3. Read the thread and you'll see that's a common observation.

Are you positive those are OEM coilpacks? If someone stating changing the KS it's only because you'regonna be in there.....You had any KS CEL codes did you? You should try installing all your coilpacks with dielectric grease @ the sparkplug boot seal.....What kind of plugs are you running BTW?Check out partgeek.com dude!

Because if the knock sensors bad it will send bad signals to the ECU; and the ECU sends erratic codes to the fuel system and makes it seem to be a bad injector. In fact since you have had injector problems before & you only have 79K miles, I would change it first before injectors. If it's located beneath the upper & lower IM; then your gonna pull those & you have to replace the gaskets when you do.
