Step 1. Undo the clamps on either side of this U-Shaped hose, then remove the hose.
 Step 2. Undo these 2 screws, it will allow you lift up the intake pipe giving you more room.  Step 3. Loosen the 2 adjustable clamps on the hose connecting to the plenum, also the other small one seen in the picture.  Step 4. Disconnect the loom plug (may vary in appearance). Then just move 2 disconnected looms off to the side. You don't have to remove the 2 circled screws.  Step 5. There are 8 allen screws to undo all the way along the plastic cover as circled below. Once you have removed them all you can then slide out the plastic cover.  Step 6. Once you have removed the plastic cover you'll see the lead pictured below, with 6 looms connecting to the top of each coilpack, undo the looms that connect to the top of each coilpack. Then remove the small screws that hold the length of cable in place and remove it. (Coil Pack Lead)   Step 7. Now, at this stage you will see the top of each coil pack, I pulled out the whole cradle and coil pack as described next but you dont have to that. You can just remove the screws that hold each coil pack in. This how to pull it all out. Unscrew the gold/bronze bolts that hold the coil pack cradles in place. There is about 6 or 7 of them. Once they are removed you can pullout the coilpacks and cradle to see the spark plugs underneath. (Top of Coil Packs)  (Coil Packs and Cradle)  Step 8. Now that you can see inside, it is recommended that you spray some compressed air inside to clear/dislodge any crap that may fall into the combustion camber once you have taken out the spark plugs. Now remove the spark plugs and put in the new ones! Step 9. Put it all back together. |
