Side Gaping Spark Plugs
Side gaping the spark plug allows for the spark to travel down and forward instead of just one direction. This allows for a better burn of the fuel, thus giving more power and increasing gas millage.

This is a fairly simple modification and doesn't require too much work, time, or too many tools. I highly suggest using this method along with Indexing for the most efficient "burn" of the fuel. I've noticed that after Side Gaping and indexing the copper spark plugs will run just as well and if not better then Platinum's and Iridium's but for far less in price!
Original How To on the web.

As you can see the ground electrode is blocking the fuel expansion, you want it to hit the freshly entered fuel, not the exhaust side where some exhaust gases are still left over. Plus side gaping allows for the flame front to go down, thus helping it expand faster.
Tools
- Sharpie
- Dremel or something to cut metal with precisely
- Spark Plug Gaping Tool
2. Take a sharpie and mark the amount that you want to cut off.
You want the ground electrode to end where the spark plug's center piece begins.
3. Properly bolt down the spark plug so that you don't have to hold it by hand when you use the dremel.
4. Now Dremel sells cutting bits, you will need one of those, they cut through the ground electrode like butter
5.All done with the cutting
6. Now you want to adjust the gap, the original manual calls for a .010 reduction in the gap, I would play around with the gaps and see which ones gives you the best SOTP or MPG results.
Install them in, Index them, and you should be getting the best you can out of your $2 spark plugs!
Onto the Dyno numbers...
Now unfortunately I do not have a graph for the non-gaped plugs that were just indexed, but I received 2whp by just indexing, then 5whp more by side gaping.
