As a follow up to all the flack I've gotten from some of Facebook's friendliest people...
The color matched cover plate was the best design solution idea I had when I began making this product. It was intended to cover and the fender hole cut. It was color matched to the fender to look like it wasn't there. That worked fine while I was shipping 4-10 per week. The demand had grown to 30-40 per week and welding was taking up more and more of my weekends. The new grommet design is also designed to dress the fender cut while NOT covering the factory plastic paint with something the exact same color. So basically, instead of covering the factory plastic with a plate, the grommet allows the factory plastic to be seen with minimal coverage to dress the fender hole. And with a flat top on the grommet, the prefilter can set directly on the grommet for the lowest possible profile.
Yesterday evening was so nice. Since I didn't have to weld I was able to box up products so that once an order is placed I can grab the box, stick a label on it and ship it out. A much smoother operation now that I had the time available to organize and prepare products for shipping.
And to address not changing the pricing for the new design...
My most similar (unnamed) competitor sells their prefilter kit for $278 or $325 depending on which filter you order. Knowing how much the similar components cost, their profit markup is WAY beyond my markup. If I were to follow with the same markup my kit would retail for $650!
