Hidden HORSEPOWER in Side Gapping your Spark Plugs?

[savatreatabvr]

I first heard of "Side Gapping" spark plugs here on this forum, it made sense to me so I tried it on a fresh set of plugs. Before I got started I read articles on SG that explain exactly how to modify the plugs in detail and also say racers have been doing this since the 60's to increase performance, well I'm quite disappointed with this SG trick because it did nothing for my performance. I wasn't expecting a major gain in horsepower or gas mileage but I expected something, anything, I just didn't see it! I hope you guys have had better results SG your spark plugs, I'm not impressed!
