does anyone know how to get to the sparkplugs on a gt4 can see them but intercooler is in the way, not sure what to disconnect?

There are three bolts on the chargecooler which need to be undone, you'll also need to undo the hose clips from the turbo and the throttle body.

It would be wise to disconnect the electrical connector for the chargecooler level sensor aswell.

Then the chargecooler can be twisted out of the way - don't pull the whole thing off otherwise you'll have to refill all the coolant.

You can access the plugs without fully removing it >>

Hope this helps
