Changing the spark
plugs in your 3.3 V6 (VG33E) is no easy task. Why is it so difficult?
Because of the pesky 6th plug that’s located in an almost
impossible to reach location. This is
the process I used to get at my 6th plug.
Do yourself a favor and make sure the engine is completely cool before
attempting to change the plugs. |

Figure 1 shows the wrench setup I used. It consists of a 3/8” drive ratchet, two 3” extensions, one universal, one 6” extension and a 5/8” Spark Plug Socket. Of course you can substitute the two 3” extensions for one additional 6”. A Spark Plug Socket with a rubber insert to hold the plug is necessary. |

OK, follow the spark plug wire back to the point where it disappears between the engine and the firewall. Reach your hand down along the wire as far down toward the plug as you can reach. Pull the plug wire off of the plug. The wire comes off very easily just as long as you pull it straight away from the plug. If you are pulling it at a slight angle it won’t come off! Locate the notch on the back of the firewall (Figure2). This is where you want to insert your wrench setup. |
| It's going to take a few tries and a little finessing to get the socket onto the plug. When you do get the socket seated on the plug you will have to stuff some rags or a small block of wood between the firewall and the extensions to get the leverage you need to loosen the plug. Place the rags right under the notch in the firewall (Figure 3). This should do the trick. The plug should come right out. |

Insert the new plug into the socket and carefully guide it
into place. Be careful not to
damage the gap on the new plug while re-installing. |
