Used this alongside the GM ethanol sensor on a custom fuel line setup and it worked perfectly. Seals well, rotates smoothly and locks in position without any movement under pressure. Exactly the kind of quality you want on a fuel system component.

Absolutely impressed with this FlexFuel kit. Installation on my N54 was straightforward, and the open wire setup worked perfectly with my custom configuration. Ethanol readings are consistent and the car adapts flawlessly between pump gas and E blends.

I’ve tried other ethanol monitoring solutions before, and this kit is on another level. Plug quality, sensor accuracy, and overall reliability are excellent. The car runs smoother and tuning adjustments happen seamlessly.

Bought these to tidy up my ethanol sensor setup and they delivered exactly that. Both quick connects feel solid and there's no play in the connections at all. The 360 degree rotation is genuinely useful when you're working in a tight spot.

If you run MHD and plan to use ethanol blends, this kit is a must-have. Accurate readings, easy installation, and reliable operation every single day. It’s obvious the system was designed by enthusiasts who understand these platforms.

Precision Raceworks quality is always consistent and these fittings are no exception. Snap in easily, rotate smoothly and seal perfectly. Made the sensor install much less fiddly than it would have been with fixed fittings.

Fantastic product for anyone serious about tuning their BMW. The analyzer responds quickly, the install guide was easy to follow, and I finally have confidence running different ethanol blends without guessing. Highly recommended.

Fitted this as part of a FlexFuel install and it made the routing so much easier. The ability to rotate the sensor to any angle means you can get a really tidy result regardless of where you're mounting it. No leaks, no issues, solid piece.
