In this video, we show you how to replace the spark plugs on your 2nd Generation Tundra with the 4.7L V8 2UZ-FE engine. It's become apparent that there's more versions of the 2UZ-FE engine than I was aware of. I knew of the big difference between the Non-VVTi models and the VVTi models, but now I found another variation. On my brother's 2007 2nd Generation 2wd Tundra, his 2UZ engine has VVTi, but instead of having the secondary air injection switching valves under the intake manifold like I've seen on my buddy Thanh's GX470 with the 2UZ engine, the air switching valves are bolted to the valve covers.
I did some further research on this 2UZ-FE engine that has the secondary air switching valves bolted to the valve covers, and what I found is this setup was only for 2nd Generations Tundras from 2007-2009. As far as I know, no other Toyota or Lexus models that came with the 2UZ-FE engine, and also had the secondary air injection system, had the air switching valves bolted to the top of the valve covers. All the other models have the air switching valves in the valley between the heads under the intake manifold.
