Need confirmation that I'm buying the correct parts

[ngood1]

Check engine light came on for the first time yesterday. Here are the codes:

16684 - Random/Multiple Cylinder Misfire Detected. P0300 - 35-00
16687 - Cylinder 3 P0303 - 35-00 Misfire
16542 - Oxygen (Lambda) Sensor B2 S2 P0158 - 35-00 Signal too High
17530 - Oxygen (Lambda) Sensor Heating; B2 S2 P1122 - 25-00 Open Circuit
17548 - Oxygen (Lambda Sensor; B2 S2 P1140 - 250-- Internal Resistance too High

So it seems I have a misfire and a bad o2 sensor.

Are the Bosch 7402KT spark plugs good?

As for the 02 sensor, I don't really want to splice the universal bosch sensor into the old one. Can someone provide a link to the correct sensor I need?

Thank you in advance.

Also, shout out to Exit 11 in Rush, NY for using the Vag-Com

Why would you need spark plugs? Nope you're not buying the correct part.

Secondary O2 sensor http://www.amazon.com/Bosch-16073-Ox...ds=16073+bosch

Likely a dead coil pack on cylinder 3, not a spark plug issue.

Multiple misfires makes me think you have a boost leak somewhere and probably an oxygen sensor on the way but i suggest you do a boost leak first and make sure that is not causing your codes before you start buying things, if that checks out, buy ngk spark plugs, and clear your codes to make sure they dont come back in, i think the key in here is multiple misfires so focus on that

if your car is stock check the throttle body boot for tears. Remove it and inspect.
