Continuing on from the last video, in this video I will be replacing the upstream and downstream oxygen sensors, the spark plugs, and spark plug wires on my 2009 Chevy Impala with the mighty 3.5 liter 3500 V6. This procedure will be identical if you have the 3900 (3.9 liter) V6.
Torque specs can be found here:

I would highly recommend you purchase a magnetic spark plug socket:

And I can't stress enough, ALWAYS BUY ACDELCO SPARK PLUGS AND WIRES!!
ACDelco Spark Plugs (Qty 6) - 12681662 or 41100
ACDelco Spark Plug Wires - 19417611
I went cheap with the oxygen sensors. Cheaping out here will not affect the engine's performance, but you might have to replace them sooner.
Upstream Sensor - ULTRA-POWER 2344668
Downstream Sensor - ULTRA-POWER 2344254
O2 Sensor socket - www.amazon.com...
