Appreciate E-Mag

[flightlogic]

Changing plugs today on the 9A and I got a little too enthusiastic with torque. The plug adapter, for the P mag (automotive spark plugs) came out in two pieces rather than one. I called and Brad answered right away. He explained how little metal they have to work with dimensionally, in order to machine such a part. He then offered to send me a replacement at no charge to get me back in the air right away. What a great company !
I still have the broken adapter to remove from the cylinder head. Have put a sacrificial NGK plug back in the threads with some JB Weld. I hope tomorrow, after drying... it will all come out together and go right in the trash.
Just wanted to post my good experience with a vendor today on Van's.
Cheers to all and happy holidays.

Why won't an extractor work if epoxy doesn't.Should be able to get at NAPA or Harbor Freight.

BTW, also can't say enough good about Brad at Emag.

That will be my next step if the glue does not back it out in the morning...
Thanks for the TIP !!

A permanent fix for this is to purchase your adapters from Lightspeed. They have this part figured out.

Why would you install the same defective part?

You must use anti seize on both threads every time you R&R the plugs and adaptors. Some heat will loosen up the stuck parts and should make them easier to remove. Good heat gun or small propane torch will work. Be careful with a torch.

You should never need to remove the adapters unless you are changing the cyl's.

I'm just at about this point where I need to decide if I stay with the aviation plugs, or switch to auto plugs. Do you know what is different about the lightspeed adapters that makes them better?

They all look very similar to me:

True. But the important part is when it comes to cylinders and threads, anti-seize is the rule, not the exception.

Also looking at all the links above, I'm not sure why any of these adapters would be brass. Makes perfect sense to me that this part should be steel to expand at the same rate as the sparkplug, not to mention thread durability. AL to brass to steel makes no sense to me. Maybe someone can explain that.

SDS also offers plug adapters both for normal and long reach plugs.

I have used the Emag versions in the past as well as Robert's (EFII). Both without any failures.

However, to the point of this thread, yes, Brad and company are first class.

Brass is used to help prevent plug seizure, has decent tensile strength, good heat transfer, reasonable cost and good compatibility with the other material here. Not sure how/why a well designed one made of proper material would ever break, especially at the torque values used.
