Piston Technology!! Casting vs. Forging READD!!

I hope you've all been paying close attention to the BIG Picture... Not all pistons (or engine components) are created equally. When manufacturers designate a certain material and design for a piston, they do this after a very well thought out decision making process which involves questions such as: What is the primary purpose of the overall final product? How much will it cost? How long do we intend it to last? What kind of gasoline do we suggest get's used by the consumer? Will it be easy to service? Ferrari and Honda produce vehicles: Correct. Ferrari and Honda ask themselves the same questions: CORRECT. Ferrari and Honda produce a great vehicle: Opinions may vary. Ferrari and Honda produce super cars for a high end market: Depends. Ferrari and Honda make two entirely different products: YES. Please consider the differences!
