If you have a 6MT and have not yet changed to the ZHP knob you are missing out... I had a E46 ZHP in the past and loved it. The problem is I wanted an illuminated knob and didn't feel confident in my ability to perform surgery on the OEM one. I also didn't want to pay the crazy prices some of the vendors are charging to modify them.
I took a gamble and bought this off of eBay.
I'm pleased to report it is an OEM model that has been modified to be lighted and very well done. It ships from Germany so it takes a few weeks to get here. Install was a breeze per the various DYI threads on here. The color of the illumination is a little bit more red in color vs the factory knob but it is very bright, not all like some of the DYI folks mentioned. It looks great overall and feels amazing to shift!
If you have not done so...Do it!
