PIAA is over-priced and over-rated nonsense.
Sorry; but I've just been down this road too many times before. Don't waste your time with hype.
Phillips makes the best drop-in replacement H13 bulb with their Xtreme. You can unleash more of its potential by using a supplemental harness and using the stock wiring to trip it via a relay.
But, best yet, an H4 bulb in a Cibie reflector with supplemental wiring will really impress you. Put a set of Osrams in it.
