Plugs went in easily and the truck runs better after 138k with originals. I just love working on the cruiser - everything is accessible and well laid out.
For those that have not done this yet it's very simple but you may want to have a couple of "special" tools handy.
my tool list:
1/4" ratchet drive
1/4" 3" extension
1/4" 10mm socket
1/4" 10mm deep socket
3/8" ratchet drive
3/8" 16mm Spark Plug Socket
3/8" 3" extension
3/8" 6" extension
3/8" 9" extension
3/8" universal extension
Shop rag
Diet Mountain dew
Passenger side is super easy to access - tons of room. Just remove the black box by unplugging 4 small hoses and removing 2 10mm bolts. Release the clamps on the engine intake and airbox output - Boom access to the first 4 cylinders. Remove the coil pack bolts and pull the packs up to reveal the spark plug. I recommend doing this one at a time to minimize mistakes.
The drivers side is more challenging as there is a bracket covering half of 6,
all of 7 and half of 8. No problem, undo two 10mm bolts and the bracket is free. Plugs 5 and 6 are a breeze. Plug 7 and 8 needs a "special" tool:
Plug 7 Tool
Plug 8 Tool
I was able to use a couple of differnt extension lengths with the universal and got 7 and 8 out easily. Start to finish including the air filter was 70 minutes.
