Here is a tank we built for the E60 535. The aluminum plate over the tank itself was required to span the space under the trunk cover so it would have support. We decided to cut the M logo out of the plate along with the hole for the filler. After that backlighting was added so the filler would be illuminated in the trunk, to avoid spills of course. Once the lighting for the filler was in, the logo was lit and a couple of different options provided to the customer for the final look. The customer will take care of painting the plate to match the car locally. Which is the better look, the M colors or the carbon?

New Viper tank ready to ship to an eager customer. Designed to fit in the rounded cut in the rear trunk.

We recently had a customer wanting a nice battery box to match his Twin Tank enclosure he purchased from us. Not to disappoint, we built an enclosure to hold his Optima battery. With an HDPE liner, red LED to match the liquid tank, and false caps to complete the look, it came out pretty nice. The battery box is on the left and the meth tank on the right.

We are putting together a tank for the Viper. Just a few shots of us trial fitting parts on the bench. This will fit in the small round area in the back above where the spare tire resides. We will post more pics as the unit comes together in it's final form.

We have updated the HFS-4/3/2 product pages with a new jet configurator. You can now receive credit on your order for deleting extra jets/tees, etc. Try it out, you may save a few dollars. http://www.howertonengineering.net/catego/AQUAMIST-SYSTEMS/

The HFS-3 was upgraded to version 3 recently, we have been shipping them for a few weeks now. The new controller can be denoted by the red circuit board inside. Many of the minor features that were exclusive to the 4 were brought down to the 3 during this upgrade. The 4 is still the kit to use for DI cars, but the 3 now has many of the jumper settings and other minor features of the 4. If interested in more details please feel free to contact us.

New tank prototype on the bench for fitting. Can anyone guess what it is? Has a sump in the bottom AND the pump fits underneath!
