If you're running E85 or ethanol mixes in your B58, B48, B46, or B38 equipped BMW, you need this kit!

As many of you know the BMW motors can be very picky about how much ethanol you run to achieve peak performance but not run lean. Consequently, we have put together a kit enabling you to easily install an ethanol sensor with no permanent modifications needed. You will simply remove your low pressure fuel line in the engine bay and plug in our kit. It's a complete plug-in solution that utilizes our Bluetooth app to monitor your ethanol content. When you are ready to return to stock, you will simply remove the kit and re-install the stock fuel line.

All of our complete kits include the following:

  • Genuine Continental® ethanol sensor
  • One stainless steel braided fuel line with black nylon sheathing to protect your other engine bay components
  • Proprietary custom billet fitting for plug and play OEM integration
  • One custom wiring harness
  • One tube of SuperLube® for hose adapter install

Complete Kit with BMS CANbus ECA includes:

  • Our new CANflex LED ECA to display current ethanol content
  • Legacy 5V output for JB4 integration
  • Universal CANbus harness for use with future flash tuning integration

Love these for beach foot protection!!
Size: 10-11 Women/9-10 Men, Color: Black-w001
These water shoes were perfect for our cruise to Grand Turk. The beach was a little rocky once in the water & the bottom of these shoes protected our feet and made it comfortable they dry quickly they are lightweight and easy to pack and carry in a beach bag. I bought two pair of the black one for me one for my husband, and he even wore them which was shocking into me and loved them.!!!! they don’t have walking support so they’re definitely something that you bring with you put on your feet before you enter like water where you can’t see the bottom or rocks/coral and they totally protect your foot on the bottom

I received someone else’s returned product
Size: 7-8 Women/6-7 Men, Color: Sunset
The inner product packaging was already cut open and not sealed, and there was debris inside the socks: clear indicators that the pair I received was someone else’s return. They also run big and are very wide in the toe area. My daughter’s pair also ran big, but at least hers were sealed. Overall quality is a bit flimsy, so we’ll see how long they last.

Decent water shoe
Size: 10-11 Women/9-10 Men, Color: N-laser Stripe
I have to admit, I was a bit skeptical about the quality of and comfort of these shoes because of the cheap price. However, I really do like them. They stay on my feet, are comfortably and non-binding, which is saying something because my feet have been pounded over the years. They even did well when I had to cross some rocks, trekking back to the kayak. Definitely a gods water shoe for a good price.

Perfect!!!
Size: 7-8 Women/6-7 Men, Color: Black-w001
I absolutely love these water shoes. I wear them around the house, getting out of shower, even outside. I’m a stroke survivor that was paralyzed. One of the biggest hurdles of walking again is feeling the ground . One day I thought water shoes would work. After trying a few types I fell in love with these. So easy to put on. Comfortable. Feels one nothing on . I’m buying in multiple colors . Love love love these. Game changer for someone learning to walk again. My feet don’t sweat in them . I wear with and without socks . Easy to wash quick to wrong put and dry. Non slip.

Good starter
Style: KIT
The chemicals are 5 stars, because the Chemical Guys make great and effective products. And they always smell good, but the taste doesn’t match the smell. I wish it came with other chemicals in the kit. But honestly go buy them one by one and get what you need.
