I've pulled the intake manifold to do it, but I understand it can be done without actually removing it. You might be able to get easier access to them from underneath. Any way you do it it's not very easy.

Just take the upper intake air chamber off. That, and the throttle body need to be cleaned anyways!


If you're really stubborn and want to reach to do it, you need one of the flexi shaft extensions and a normal joint. Oughta be able to worm in there like that.

you can change out the back spark plugs if you use the right combo of extensions and swivels, I have done it. The #3 and #5 cylinders are the worst because they are directly underneath the intake plenum. This saves you from having to pull off the intake plenum and replacing the gasket for it.

only other thing I can say is be patient cuz it's not easy but it can be done.
