OK, I am almost embarrassed to post this, but I hope it will save someone else the pain in the tail of broken spark plugs when gravity decides you should go rubber side up 
At a recent Monster Jam show, I was running my MT off the big ramp (you know, the one meant for the 10,000 lb monster trucks LOL) and ended up landing rubber-side up. Aside from the obvious damage to the body, I also hit the roll cage inside, forcing the metal plate into the top of the spark plug boot, cracking the plug. Luckily that's all it did, and did not damage the threads in the head! If you look, you can even see the dent in the metal cover from the impact as well...
So, since I had some PVC pieces from other projects lying around, I decided to make a spark plug protector. I took a 1/2" PVC T fitting, and shopped 1" off one end, sprayed it with truck bed liner I had lying around as well, and wala - instant plug protector. It looks pretty good - I could make it a bit nicer looking by being OCD-like in my cutting, but since it is under the plate, I didn't care TOO much about the final look...
The T-fitting fits around the plug and the plug wire as well, putting the PVC higher than the plug wire, so it will take the hit instead of the plug. Yes, this will cause the pressure to go onto the plastic head cover on the motor, but better than smashing a plug into the head and destroying the threads. Obviously this is not a fool-proof solution, but it does help to protect against all but the hardest hits
Hope it helps.
