Spark plug size

The tool i listed is a threaded steel tool that is made to thread into the deep shoulders of the HEMI. The air hose connects directly to the tool with standard air tool fittings, no hunting around for adapters or special fittings. What kind of compression tester can you get for 25$? My Snap-on unit was 250.00$, i would not trust that Chinese testers, so that would be an expensive hose, verses a quality steel tool that will last forever. Besides, most compression testers come with multiple threads to fit both size plug holes, these will not work on the HEMI, the shoulder is too deep. I used to be a mechanic, i learned A long time ago that quality tools are worth the extra money, you will have to buy cheap crap over and over again.
This is a pic of the compression tester I have and have had for years and used on many occassions. The adapters that come with the tester will work. Believe me, I just used mine to change my springs on the heads. I agree with buying quality tools but were talking about one tool you will use ONE time. Once he changes springs he will never change them again for than likely.
You can buy that tool at sears and its cool to have. I just think for a few bucks more you might as well buy a compression tester that will be able to be used for the heads to change the springs and used for diagnostics later on if needed. Like I said, youre only going to change springs once.
Not trying to ruffle any feathers, just stating my opinion.

I am not upset at all. All i can do is throw an idea out there, weather some one chooses to use the idea has no impact on me. The tool i listed is an extension for compression testers designed to allow access to deep plugs. It is not just for changing springs. This will work on any engine where the plug sits deep in the head. The steel tube allows for greater control when doing compression tests as you can tighten the tube much better then simply screwing in a hose. This makes it much less likely to have an incorrect reading from pressure bypassing the o rings.
here is one on Amazon for 13$

Thats cool. For $13 though I would do it. And if Im not mistaken, I thought Frog once posted a pic with a metal rod going down in the cylinder. I always wondered how they did it or what it was. When I did my cam I was trying to find something like this and no one had anything and then I found my compression tester and realized it would work.
Nice find though Horseapples
Im sure you could buy it and resale it on the boards here once you are done using it.

personally, even if i am going to only use a tool once on my own vehicle, i still buy a quality one, even if a cheaper one is available. that way i can keep it in my tool box, and down the road if anyone else in my area needs help doing something that requires that tool, then i already have it. and what i get out of that, is more experience. same reason i purchased spring compressors and a Pitman arm Puller. i used them once on my truck, and a couple more times on my buddy's trucks.
