how do i change rear spark plugs?

Hello,

In order to have access to the plugs at the back you will have to first remove the wiper arms and the windshield cowl.
This will give you just enough room to get the spark plugs out.
It will still be very tight, but it will work.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
