I now use the same Denso L-14U (against Klaus' advice) with no issues.
The only problem I have ever had with the adapters was when I followed the advice of someone with a Light Speed Ignition who told me to install the adapters and torque them down and then install the spark plug, like Klaus recommends. I crushed the adapter and had to order a new one from Emag. Installing them on the plug, using anti-seize on both the plug & adapter, and then torqueing the plug, as Emag recommends has worked fine.

Bob,

Are those plugs really as hot as this chart would seem to imply?



Thanks,
David

Default inserts

Torque the inserts to 35 and the plugs to 25. No problems.

Do NOT do this with inserts / adapters from Emag!!!
If you do, you will crush them. Just ask me how I know. (See my post at the top of this page.)

Note 1: If you install and torque the adapters separately, stresses will be
focused at the adapter neck and can cause it to fail during installation.

It seams that Lightspeed and Emag get their inserts from different vendors.

When I tried to install my Emag adapters per Lightspeed's recommendation I crushed the first one and part of it almost fell into the cylinder.

This delayed some flying and almost forced me to pull a cylinder.

Since then, I have been installing per the P-mag Installation Manual and have not had any issues.

It is best to follow the manufacturer's recommendation, even when using parts that look to be very similar.

Default agree

Have pulled and changed plugs dozens of times and never had a insert come out. Marc

I had some bizarre PMag behavior last year (documented on this site) and finally traced it directly to the use of non resistor plugs. The non resistors would partially shut down the PMags in short order. Switching back to the recommended plug fixed the ignition immediately. It did this on four, count them, FOUR separate ignitions.

Non resistor plugs and PMags are bad juju. Period, dot!

Of course it was only AFTER I found this all out that I discovered the NGK warning about non resistor plugs and their potential to screw up electronic ignitions.

Default NKG Spark Plugs

Here is some interesting information on NGK plugs.

http://www.ngksparkplugs.com/tech_su...x.asp?mode=nml

Provides a good understanding of how the spark plug choice affects the engine(plug fowling, overheating, compression, altitude, etc.). Of course this is regarding earth bound vehicles, but I can see the relationship with aircraft engines too.

I have dual P-mags on my 0-320 and use NGK BRE8ES plugs. They are so cheap that I replace them at conditional inspection even though they are in great condition.

I now have a little bit more experience with the L-14U plugs. Not sure if I will continue long term with them, they seem to be running on the hot side.
