Spark Plug Install

[jaysinstrife]

So here is the deal. My dad and I are installing stage colder plugs from Tune+ but the plugs don't seem to be setting. We are getting, what feels to be, no torque when installing the plugs. They seem to start to tighten, but then it loosens back up. We can't pull it out with a plug socket so we would have to guess that they are in there really well. Anybody else run into this when changing plugs?

Mind you we aren't noobs by any means. Are these just that deep or ?

Are you saying that they won't torque up at all or are your describing the feeling while threading them in? If it's the latter, that's normal. If it's the former...you're in for a bad day unless your OEM plugs can torque up.

My normal plug socket doesn't fit when changing plugs on this car.

I use a normal 5/8 socket (I believe that's the size) to loosen and tighten the plugs.

I use the plug socket to take the spark plug out/start the threads. Then I have to switch over to the normal 5/8 socket again. Hope this helps

Oh, I understand now. It has something to do with the head because I had to do the same. Spark plug socket to get the plug in/out but a regular socket to torque/break torque. I never took a micrometer to the outside of the two sockets but the spark plug socket definitely doesn't get all the way down.

We got the stock plug to torque down.

Does the socket plug make the plug just spin in the chamber? Hence the use of a standard 5/8 socket?

Try using a normal socket to torque it down. If not I would try to shine a light down there. Hopefully you didn't cross thread the head !

I had to do this too

I would hope since the sticker went in that it wouldn't be cross threaded. I'll give this a shot with a standard socket and see what happens

Odd... The spark plug socket I use (5/8, Craftsman) does the whole job.

No, the head just doesn't allow the socket to come all the way down with the spark plug. Basically, you thread the plug further down than the socket can go before it will torque. It must just be a pretty close tolerance compared to the outside diameter of some spark plug sockets.

Did any of you guys use anti seize on your plug swaps?

I do. Just a small amount.

I ran into this issue awhile back. Not all sockets are made the same. I also used a dab of antiseize.

UPDATE: Got it all installed! The socket swap idea was golden. Used a small amount of anti seize as well. Drove for about 60 miles and it seemed to be running just fine. Didn't notice too much of a difference. Now once I data log after this oil change I can send the files to Adam and get my tune touched up! Thanks for the help everyone.

I just did mine this past weekend and never had issues. Stock plugs came out easy and the Tune+ plugs I initially installed with a 5/8" socket wrench attached to a 6" extension and tightened them by hand as far as I could, then did a final 1/4 turn tighten with a socket wrench.

FYI I got this socket set from Amazon and it worked great for me.

Thanks to all for this thread.

I just changed mine, very odd situation and I know I'm not the first. They come out no problem, but at least in my case, even using the proper size spark plug socket, they will not turn in all the way. The socket prohibits this. The shaft that the plug sits in is so narrow in circumference that the socket can't get in there and therefore the plug won't turn all the way. I ended up taking a dremel to my socket and shaved off a bit of the last 1/2" all around, making it slightly thinner, which allowed it to enter that channel/shaft and for the torque wrench to click. Car seems to run fine. Very odd...........word to the wise.

Maybe the craftsman tools others have referenced are made differently than what I have (off brand spark plug socket set) and therefore work....gonna have to get a set for next time.

I have ran into the same deal as others. Takes a longer 5/8 socket with a tight tolerance. Other wise the spark plug won't sit all the way down. Also use antisize. It helps the new plug thread in smooth. I notice that carbon build up on the old plug threads
