What is the difference between normal and performance spark plug, and which would u recommend?

i have a 2000 mercedes s430, i have reached the 100,000 miles mark on it and i was told that i need to change my spark plugs, i was looking online and i found many different types of spark plugs, and i was wondering which one would be the best to go with, the original (bosch) or a preformance one, (many different brands) , i would really appreciate it if someone could help me and tell me the diffrences and recommend a type.

The High performance plugs provide a stronger spark basically.Will improve your mileage and power a tad,but for what you need I wouldn't spend the extra $

The design of the sparkplug is different, but all it does is improve the %26quot;reliability%26quot; of the spark. A spark is a spark, nothing more is needed. I'd just stick with the Bosch. I have not seen any improvement by using performance plugs vs originals. Now if you had a true race car, like a Corvette, my answer might be different....
There are a couple of differences. Some provide a larger area for the sprark to make contact with. some provide a hotter spark. Usually the extra money that you spend on them does not make up for the performance. Personally I put NGK spark plugs in everything that I own. They arent the cheapest or the most expensive but in my experience they are the best.
sounds like the plugs you have been using are working fine.100,000 miles is good. don't change what works.
None whatsoever. Performance spark plugs are pure snake oil. Get high quality platinum versions of the originals.

Car makers don't spend hundreds of millions of dollars improving engine performance 5% when two dollar spark plugs would have done as much.
