I know the factory stamps/ etches the three-letter code somewhere on the head area of the engine, but I cannot locate it on this car...is it perhaps somewhere else?

Anyone know where to look?


Also, I wanted to change the spark plugs and I'm trying to find a "how-to" on doing so. There's a bunch of various engine components covering the plugs up.....any tips, tricks or suggestions?

THANKS a TON!
