Hey guys, I hit 60k recently and wanted to get the spark plugs done. It was pretty expensive at the dealer, so I decided to do them my self. There were a couple youtube videos that were semi helpful, but I figured I’d document something a little better here.
To start, you will need the right spark plugs. I like to use the exact OEM that ships with the truck. In this case it’s the Denso FK20HBR8 Spark Plugs.
I used some dielectric grease and a bit of anti seize grease on the threads of the plugs.
Tools needed: a good socket set with long shaft attachments I had to connect multiple together. The passenger side is easier to get to than the driver side. You will need a spark plug socket to safely remove your spark plugs.
Disconnect your battery for safety!
First up, the passenger side. It makes it way easier to remove the intake. Disconnect the hose attached to the intake and unclip the wire harnesses and you will be able to move the intake out of the the way.
Next locate the three spark plug boots. You will remove the clips to disconnect the wires from them and then remove the screw on each one. You may need to remove some wire mounts to make things easier. You will be able to pull the boots straight out. Now your spark plugs will be exposed.
Use a spark plug socket to remove the plugs.
You can now put the new ones in and assemble the wires. I torqued mine to the denso spec which is found on the side of the box. Hand tight then give it a half turn snug. I found some specs online at 12 -15 ft lbs, which I have not confirmed. but I did the the hand tight method and all seems good after a couple hundred miles.
Move on to the drivers side. This is where it gets a bit more difficult. There are two brackets/mounts that hold the intake assembly in place. You will need to remove the top bolts and the just loosen the bottom ones. This will allow you to move them out of the way and get to the boots. Disconnect the needed wires. I also needed to move hoses from their brackets to move them out of the way. I disconnected a small hose under the intake
this foam piece is in the way. You will need to unbolt it to remove it.
putting in the new plugs!
Just follow the steps in reverse to get everything back together. Double check all your connections and give it a go.
