Can anyone ne tell me what size spark plug socket I need for my 73 2.4 before I head to the tool store.

13/16"

13/16"

Smallest OD you can find to fit number 6.

A word of caution if you've never changed plugs: if using a regular socket and extension (depending on your socket and extension) the spark plugs have been known to fall out of the socket or the socket come off the extension leaving them down in the head where they can be a real pain to fish out..

Do you have the factory spark plug tool in your tool kit? It is the best for this job.

Looks somewhat like this:

You can also get one of these:

Stahlwille 1052

Hazet 2502-2

Cheap solution is to use electrical tape to ensure the plug socket stays attached to the extension, but I like the look of the Stahlwille/Hazet sockets. Something else I didn't know I needed until now.

get a locking extension.

Anyone using a magnetic socket to retain the plug? What's your experience been? Good / Bad?

plug socket
 

Stock factory socket tool is a must,from 84 with spring is really good as it
has inside socket a rubber grip to help hold the spark plug when removing.
Also there are regular 13/16 sockets that will work as well that have rubber inset.
The rubber is also a must, because with out it you can crack the porcelain. and will cause a miss with that plug.http://forums.pelicanparts.com/uploa...1488796745.JPG

Wayne nailed it. Need the regular extension plus a bit more. I use the wiggler (CV) to add a bit of length.

I've been using a magnetic 13/16" Snap-On socket for over 20 years, had to replace the magnet once, but no other issues. Also have the 5/8" version

mine is like waynes bottom pic.
3in extension with a swivel.
trick is to WELD them together.
when putting plugs back in it can come apart
you need the swivel to get the tool in and out of the hole.

the spark plug socket should have rubber inside it to hold the plug and keep it from falling out.

I have used the factory tool. it is ok. it does not ratchet not that mine need to. they spin out freely. the knurled knob on the factory tool is nice.

I use the duct tape version, been using the same one for 20 years now. Have to replace the tape once every 5 years or so, works great.

Factory Tool is #1
 

I would encourage you to find and use a factory or similar tool. The knurled top piece is key and the swivel, and no parts that can come apart encourages and makes it easy for you to do what all spark plug installs tell you to do. That is to thread the plug in "by hand" and only use a wrench for the final turn to tighten! The plug should come out fairly easily after breaking it free so ratcheting is nice but only if something isn't right. I've never needed to ratchet a plug out or in on my car. Ratchets are for emergencies.
