What a waste of time.
I am replacing the spark plugs on a 2007 RX350 made in the USA. I have spent the greater part of a day over 9hrs trying to get the passenger side bolt out of the air box. I have attached a picture and if anyone get any ideas I would sure like to hear them. I can actually get in the engine bay on my back and put my arm near the bolt but I can't even feel it as the wire loom is large and in the way. I am stuck. I will complete the front and wait for it to fall out. I have worked on SC400's, Porsche 951 (944 turbo), and even my SL500 (2006) and this is the first time I am stuck in over 40 years.
