Changing the plugs clued me into 2 other surprises...
1. The Car has K&N filters already (i've only owned it for 2 months)
2. Car has SL55 Airbox conversion!
Now I wonder what else the previous owners were up to? crank pulley and tune would be nice!

NGK-LFR6A are stock. NGK-LFR6AIX are the same temp and are a better plug for a stock motor imho. NGK-LFR7AIX are a step colder and are great for boosted motors. A step colder plug on a stock motor won't hurt anything but you will also not get the full benefit of the plug.
