LUCKY YOU:  The E46s with OEM ZKW Bi-Xenon headlights are notorious for basically self-destructing due to a very cheap plastic used for the projector bowl. Fortunately, the Morimoto Retro-Quik system is designed as a bolt-on upgrade for a big performance boost inside the headlights on all E46s with OEM ZKW Bi-Xenon headlights. 

FOR ZKW BI-XENON HEADLIGHTS ONLY!:  This kit is designed solely for the OEM ZKW Bi-Xenon headlights. Have OEM Bosch / AL Bi-Xenons? Consider the E46 Replica Projectors instead. Have OEM Bosch Low Beam HIDs? Consider the Bosch Retro-Quik instead. Still have OEM halogen headlights? Check out the Mini H1 kit instead.

BI-XENON PROJECTORS: Truth be told, for a bunch of headlight nerds: We could not imagine a more perfect projector. The all-new Morimoto Mini D2S 4.0 Bi-xenon takes the cake in every category. A supreme low beam. A High beam so bright it's unholy. A cutoff line that can't get any sharper. Quality that nobody can question, and an undeniable ease of installation. If we died and went to headlight heaven, this thing would be greeting us at the gate.

MOUNTING HARDWARE: 100% Engineered in the US. Laser cut from G10 fiberglass plate. The Retro-Quik brackets at the heart of the kit are designed to adapt the Morimoto Mini D2S 4.0 projectors directly in place of the burned stock units. Using the original mounting holes paired with new hardware, they are the beauty behind the kit that makes it an easy install. Some trimming is required here, so just a heads up to plan accordingly.
