How about returning them for the correct size.

Thought Amazon stated All sellers must now abide by Amazon's own return policy on products they fulfilled.

Good news, bad news. 4 spark plugs fit perfectly in my old Volvo. As to the Toyota, I filed down the top circular area and a 3/4" deep socket fits. However the 3/4" socket is too thick to go down the spark plug hole. I'm so close to getting this right. Any suggestions?

Do you have a link to the product for a photo?

Strangely, they raised the price to $63. I only paid $27 for a set of 8.

That's a pretty BIG price increase!

Does the socket have extra thick walls or is the issue the plug designer used a 3/4 inch hex drive and the socket diameters are just too wide?

A few ideas:

Have ground sockets diameters down to make fit.

There are "thin wall" deep sockets available. What the real diameter they are is unknown.

The plug has a nipple on top. Perhaps can attach a stiff hose, flexible hollow rod, etc. that would slide firmly over nipple. Use this to install and screw in the plug. Leave the hose, rod in place to remove plug.

Can you cut a slot into the nipple for use with a blade screw driver?

You don't need to torque down these plugs. Apply a little silicone grease to the plastic threads to aid in reducing thread friction and seal the thread contact area. Then screw in best you can without damaging the plug or making it difficult to remove.

Thanks.

I believe that cutting a hole in the nipple will expose the desiccant to room air.

I'm thinking that a 7/8" or slightly less rigid cylinder, like a hose might work.

In addition, I found these thin wall spark plugs:

Amazon describes it a 1.1 x 2 x 4.5", but the 1.1 and 2 don't make sense, the shape being cylindrical.

I just measured the width of the spark plug hole: 7/8", so I don't *think* that those thin wall sockets will fit.

Thanks!

Could try to glue a plastic pipe as a handle to the plug. Assume the plug is made from polycarbonate or acrylic.

Find a thin wall PVC pipe OD (white water pipe) at a hardware store that fits snuggle over the hex socket area and inside the spark plug tube. Or a pipe OD that fits snuggle over the plug nipple.

File the plug or drill pipe to get it to fit snuggle. Then glue parts together using a multi-purpose cement.

The pipe now serves as an extension of the plug to install it.

Thanks. I'll try them out.

I tried flexible PCV tubing, but it would not fit over the spark plug desiccator and be < 1" in outer diameter.

The problem with gluing something to the spark plug desiccators is that I need to put them into my microwave to renew the desiccant, so size and lack of metal are important.
