How to change the spark plugs on a Mazda CX-9

In this video I will show you how to change the spark plugs on a Mazda CX9. It is quite an involved process for the rear spark plugs since it involves removing the air cleaner, throttle body and manifold assembly.

Very good explanation

the coil connectors have brittle release tabs. Be very careful to clear them before pulling out the harness connectors or they will break (won't be able to secure connectors back in place)

😊Thanks, when I saw the front 3 S.Plugs were accessible, I assumed the other 3 were relatively easier to replace!!😊
Good INFO!!
Is it POSSIBLE TO REPLACE THE PCV VALVE WHEN YOUR INTAKE IS OFF?

I get the error code p0302? Is this the cylinder/ spark plug in the front or rear?
