Spark Plug Removal Tools - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Not sure if spark plug removal has been posted before, but I'll post it anyways. I took out my #4 spark plug without jacking the engine. If you have big hands, this may be very hard to do. I'm not giving a how to. I'm just showing you the tools I used. If you can get to the coil packs then you can do spark plugs. The following tools were used:

14mm extended socket (Mine was a plain socket so it did not have the rubber insert inside to grab the spark plug.)
3/8" swivel or u-joint
1.5" extension
3/8" Flex Handle

*Extra convenience tools*

13mm Gear Wrench with Socket Adapter (Used this instead of socket wrench due to low profile to fit between spark plug and wheel well wall.)
Curved tip needle nose (To pull out the spark plug. A magnet could also be used.)

Basically you just put together the 14mm socket assembly in the order as shown. The socket will fit into the head at an angle and then slide onto the spark plug. It's not hard to break loose. Once I got the plug loose enough, I pulled off the wrench (or flex handle) and started turning the socket assembly by hand. Once I felt the plug was loose, I pulled out the socket assembly and used the curved needle nose to pull out the spark plug. (You'll know the plug is loose because it will be laying down and no longer centered in the head.) It was as simple as that. I'm not sure if a rubber insert in the 14mm socket would help or hinder this process. If you try it, let us know how it works out.

Hope this helps someone. Enjoy...

Just curious why you needed to remove the spark plug?

Troubleshooting... misfires and other codes. Next up is the wiring. http://www.ft86club.com/forums/showt...=30879&page=11

Nice. Will a similar method work on spark plugs 1, 2, and 3, or are these much easier or harder to remove?

JimmyMac · 03-29-2015, 12:09 AM

It should work. Position #4 is a little tighter than #2. On side 1 & 3 you will need to remove the injector driver to gain access as you would doing a coil swap.

Dear god that plug looks beat. How many miles are on it? Are you boosted or running a super rich tune?

Carlitoz3 · 03-31-2015, 05:18 AM

Might as well do a How To while you're at it 😊

About 39,000 miles. I was having coil/misfire problems with this cylinder after turbo install. That's why I pulled it. (Turned out to be a main harness connection issue.) I had less than 100 miles boosted. Lots of unburnt gas through this cylinder. (No not through the whole 100 miles.)

Thanks. A few people had posted a list of tools, but nothing speaks better than a picture.

I might do a quick video. We'll see if I have time this weekend. If I do I'll just show you how to remove one of the plugs for the driver's side. Then maybe a separate for the passenger side.

This is my first introduction to 14mm plugs. Are they common now? All my sockets are either 16mm or 13/16(which are getting 'dusty').
