C'mon, everyone knows the cheap "xenon" blue tinted glass bulbs die in like 3 months. Doesn't matter if they are PIAA or APC. Get some SilverStars, they aren't tinted, and look just as good. (And still cheaper than PIAA's). Also, standard H4's are 55 watts (low beam). Even at 90 watts (supposedly) they will be dimmer than standards. Blue bulbs just suck, I've gone through 3 pairs in 3 months. No, I did not touch them when I put em in.
