Spark plug removal, easiest way?

[Big Peter]

Hi,

Mine is at 126k on my 450h, and need to get the rear 3 plugs out.

Looks a nightmare, what’s the easiest way, will do myself.

thanks!

To my understanding you will have to remove the intake manifold to access the rear plugs, so no easy way that I have heard of. My wife's 2011 RX350 AWD have hit 98k miles so it is time for me to tackle this job as well.

I have done a similar difficult spark plug job on my wife's old 2006 Nissan Murano AWD which required more work due to having to remove the wiper motor and cowl section in addition to the intake manifold.

 

I will use this video to help me do my wife's 2011 RX350 sparkplugs. The 2010+ highlander is very similar to our 2010+ Rx350 so same method more or less.
