If I have a torque spec, I torque it to that torque spec; I dont care what its on.

Also, that is a crazy inconsistant way to do things. Who says that handtight is the same for everyone, or even repeatable for every plug hole? I just dont understand the whole, I dont need a torque wrench cause im a badass and iv been doing this for years attitude about stuff(im not talking about you really, just a passing comment). If you have the tools, why not use em.

90° will put you well over 13-15lbft, tapered seat plugs should be hand tight +1/16 turn (22.5°).

Here's NGK's page;

and Nippon Denso;

and E3's page;

Bosch says 15°;

I was in the store in Jacksonville this afternoon and noticed the shelf was bare--every time they have them on sale (usually $20) they sell out quickly.

I know at times I sound like I work for them (I really don't), however while you are there you might want to look at this plug socket (and a 1/4" to 3/8"" adapter).

Or better yet wait 'til the plug socket is on sale (usually 1/2 price). It works very well as its length prevents it from getting canted/cocked in the plug well and damaging/breaking off the plug--it also means torque, when both removing and installing the plug, is applied on axis to the best possible extent...

I had a bit of time this afternoon, so I drill and tapped a slug of 7075 aluminum to 14x1.25mm, made a tapered seat and did a couple tests.

After running down a spark plug into the fixture at 60lbft a couple times, to form a good seat, I hand tightened it and torqued it to 15lbft (180lbin) using my 5-year old Harbor Freight 1/4" drive torque wrench--it turned a bit more than 22.5°.

I then used a Snap-On 1/2" drive dial indicator wrench to turn it to 90°. It took 47lbft to swing it 90°...
