    Has anybody tried side gapping your spark plugs. What kind of result did you get?

    Below is a picture and a link.

    It looks like the same principle as the new bosch platinum plus fours. It essentially opens the kernel to the combustion chamber, rather than shrouding it behind the ground electrode. I have never used a side gapped plug, but i do know people who have used the bosch plus 4. I have heard mixed results. Some say they didn't notice a difference, and one toyota wouldn't idle smoothly any more. Just my thoughts.

    Thats excatlly what my autolight race plugs look like. Thats how they come. It is very hard to gap them this way, and according to autolight that you do not gap them and to leave them the way they came. The gapping is tottaly different. When I put them in the car I noticed a little quicker throttle response (Quicker reactions at the track). I dont know how it would work for evryday driving though because I pull the plugs out saturday morning and put a set of regular plugs in for driving all week long. (my gas runs too rich at idle and fouls the plugs reall quick, and since those plugs are expensive I would rather destroy a cheap set of plugs) That and the heat ranges are different.

    BTW they work much better with MSD then regular HEI. The MSD can throw the spark farther.
