SUPER Thin Wall 14mm Spark Plug Socket Needed - Anyone with a lathe? Will pay!

[spyerx]

This is for a 4L Porsche 9A2 engine, porsche wants, not kidding, $180 for their socket. It has a 918 Spyder part number so maybe that is why. The plug recess is very, very narrow. The porsche tool is a 6pt, standard type, 14mm, but it is 17.4mm in diameter, the walls are probably about .75mm at the points.

If someone knows of a less $ option, I’ve looked and not found anything, I’m open to that. My BMW 12pt socket is 17.9mm and wont fit.

If someone local in South OC SoCal has an interest in cutting down a socket I’ll pay for the work and supply a 6pt chrome socket. (hopefully less than the Porsche socket!). I don’t want to bother a machine shop or my regular tech that does the bigger work on my cars for such a small job...

put it in a drill , run an angle grinder on it to reduce the OD.

 

[mike93lx]

If you can't find someone local, I'd put it on a 1/4" hex drive bit and chuck it in the lathe. Angle grinder and a flap disc til it fits.

Wear a respirator. Bet the chrome dust is not great for you

yes i considered this, on a dril, l angle or bench grinder. My worry is how thin the walls will be and jacking up multiple sockets in the process.

Dumb thought, will one of those sheet metal plumbing wrenches fit? That's well tight tho, good luck

How about $27 from Ko-Ken? They say the diameter is 17.0mm.

It's not.

It's not.

I bet it is at the other end

That special Porsche socket is made by Hazet (model 9006/1) but appears to be exclusive.

You're right.

Good thing I don't own a Porsche.

Sorry, OP.

This one says 17.7mm OD, it'll be close

Impact sockets are easier to turn. Just saying. If I still had access to a lathe id make one for you.

I saw that one in person, I don’t think it’s 14.5mm, but I’ll go back with a set of calipers.

I think that is the wrench end, the other end is bigger.

That special Porsche socket is made by Hazet (model 9006/1) but appears to be exclusive.

it is, and Hazet won’t sell it! The ones hazet does sell are too big, just under 18mm, and 12pt. This one is 6pt. Likely to keep it stronger.

Is it this?

Pardon Our Interruption...

That vas number shows up in a lot of stores.

Yeah this is a 12pt socket for other models, different socket. The part number is 918-721-900-61 and I can’t find an OEM equivalent (from snap on, etc)

Thanks guys for checking!

 

[spyerx]

This one is tiny compared to my pile of 14mm sockets (AST SP1412)… but 17.9mm! Won’t fit :-(

 

[dchawk81]

Is this it or no? The review says it fits 2015 GT3 but I don't know if that's the same clearance requirement.

Not the correct socket.


He already has a socket that's 17.9mm on the output side and it doesn't fit.

My bad. I misread the diameters backwards.

This place has it for $140, still crazy expensive for a socket but $40 off is $40 off

There are a few lurking around, but I am by no means an authority on their validity.

 

[d.mcfarland]

I can do it for you. No guarantee expressed or implied.

My only hesitation is once it gets too thin, you will damage it when torquing and then have a larger problem on your hands.

So just we’re all on the same page, this is the thread corresponding to at least one of the pictures shown in #24 / where that picture probably originated from.

rennlist.com

It’s lengthy, but also shows a machined down socket. Interesting read!

And here is another, maybe, maybe not, interesting document on the matter. And might explain why the readily available sockets by Hazet, sometimes listed as alternatives, will probably not work in this specific case.

Got a belt sander? Hold the socket with an extension and slowly turn it.

I checked my burger tuning socket, it's about 17.9mm od.

Everyone also knows most Infiniti engines require a special thin walled socket to remove/reinstall the spark plugs. This highly recommended specialty socket is all you need. The magnet is pretty cool too.

Have you considered one of those throw-away stamped steel sparkplug wrenches, the type you get for free with lawn mower sparkplugs. These POS items have helped me out a few times.

 

[RoninB4]

-That's an unusual looking spark plug. The threaded portion needs that much length to reach the combustion chamber? An odd design criteria. The grinder/belt sander suggestions would work for some applications but aren't very good for this one. A thin wall in unknown socket material could lead to fracture due to lack of OD/ID concentricity. I could spin this up, as others have already posted, but the OP should test the turned socket to torque spec in a vise before using it. Contact me by message if you want this done.

Hi all - so I'm good here. A rennlist member ended up making one he's selling for 1/2 the porsche part price (its shown in the linked thread below)... so I won't have to bother any members here and appreciate the offers and assisting in the hunt!

I can do it for you. No guarantee expressed or implied.

Agreed. Just found a member at Rennlist has made one that works so I'm buying his part from him. I appreciate the offer.

Thanks for linking to the thread over on Rennlist. That is the socket, and in talking to my shop about it, they use a machined down snap on 14mm socket for their 9A2 engine work.

Out of curiosity what's the torque spec on the spark plug

Very light torque 15nm / 11 ft lbs. Generally just enough to compress the washer and a bit of resistance on top.

And regarding this engine, I've 4 porsche sports cars (4 different generations) and this particular engine is the only one that needs something this crazy. The later GT3 need a narrow socket but not THIS narrow. The GT cars have a similar block platform but the heads are totally different on those.

 

[Bigblue&Goldie]

I'll be at Porsche in Stuttgart in October, so I was going to offer to "borrow" one from the factory. Unfortunately, I'll be there to pick out the Porsche I'll be buying used 20yrs from now......

You caused me to go check mine and the smallest 14mm plug socket I have is 17.85mm. The 2018-2023 BMW M5 has pretty narrow plug holes.

 

[Rilakkuma]

I have an older 14mm snap-on spark plug socket that is very thin wall. I'll hafta dig it out and measure.

There is a guy on Rennlist that made one with custom angle extension attached that he rents out for $30, you pay shipping one way, and said he would sell one for $75 including shipping. Here is a thread about it. https://rennlist.com/forums/718-gts...s-4-0-spark-plug-change-tool-required-12.html up. Oops, posted this before I saw you found this guy already.

If it's a six point, it's probably way too big for this purpose.
