Don't think anyone mentioned the new astro set. Definitely worth a look if you're considering gearwrench.

Have been happy with mine so far.
Yes, 94404. It should come with a plastic tray.
I bought a Gearwrench magnetic socket with built in swivel extension. Works great for OHC engines with deep spark plug wells.

After seeing all the good reviews of Koken plug sockets in various threads here, I ordered a pair this morning from Zoro.com, with a 20% off code: AUG23Another vote for the Koken sockets with the spring retainers. Like all Koken products, they're top quality.
Ko-Ken have a really good selection of spark plug sockets in virtually any configuration you want

I have seen the porcelain cracked by someone using a Snap-on magnetic swivel spark plug socket before, but I've never with one of my gearwrench and they've seen hundreds, several, of spark plugs and I've never given any thought to being 'careful' with them. I've only ever been as careful as need be with the spark plugs not to strip any threads in the head, same as I do with any spark plug socket.Be careful with the magnetic sockets, they'll crack an insulator if you're not paying attention.
always used a LONG straight spark plug boot, and/or a length of old 3/8" fuel line at the tune up shops.Be careful with the magnetic sockets, they'll crack an insulator if you're not paying attention.
I actually don't even use spark plug sockets to install plugs anymore. I use a spark plug installer. Heads are just too soft now to risk a socket on an extension crossing threads.
I got some off the truck that look like these, they aren't branded tho.
The KoKen are superb in every respect. I have found none better.I like those KoKen, but do they seriously have 20.8mm stamped on them instead of 13/16?? That would just be dumb.


I recently picked up some locking extensions for this reason. They're greatIf you are dealing with recessed plugs though, I advise the “extended” sockets rather than using an extension. The socket grips the plug so positively, that you will lose the plug from a conventional extension when you remove it.
Yes, that’s the other option!I recently picked up some locking extensions for this reason. They're great

I have to admit I really like the extended sockets - they are very “slick”, and without a joint between socket and extension I find it’s easier to avoid cross threading. Even the knurling is perfect for starting the plug by hand.
You also seem to retain the “feel” better.
Dave, do you have the extended magnetic ones or spring clip ones?The KoKen are superb in every respect. I have found none better.
Yes, they do have 20.8 on them. Yes, that is a bit daft. KoKen have a very international market, and sadly, people from some countries struggle with fractions - instead of reading the number as 13 x (a convenient small unit) they think there is arithmetic involved! Many other manufacturers from metric countries do the same.
Personally, I find the sockets so good that I forgive them! The brass bushing protects the socket well, and the metal spring clips are the best I’ve found - the socket is easy to push over plug but holds it rigidly.

In Dave's second picture, you can see the spring clip in the socket (at 10 o'clock and 4 o'clock).Dave, do you have the extended magnetic ones or spring clip ones?
Thanks
