I don't really see a difference between the OEM and PIAA super whites. The PIAA lighting -kits- have always seemed like snake-oil to me...being popular with the tuner-import crowd for their SHOW rather than their GO.
With halogens, the wattage and headlight lens are the biggest factors in light output. We see a big improvement going from H5s to H4s...just a lense change. On my Jeep, I changed the lens as well up raised the bulb wattage.
You want better performance, you have two realistic options. 1) Upgrade your wiring and run higher wattage bulbs, or 2) spend the $$ and get the real deal - HIDs.
