Great for DIY Flex Fuel Sensor
Way better than flex fuel kits. Made my own flex fuel kit for under 250 total for a 2019 bmw 330i and works perfect

Works out of the box with Hondata KPro V4
Cheaper than buying a whole flex fuel kit and worked perfectly with my KPro V4 to add flex fuel capability to my K24 swapped EG

Great product
Used for a E85 conversion on my 2010 Camaro, has been holding up so far and worked well on the dyno, great for aftermarket use or OEM

OE quality
Killer price, killer quality. Legit GM sensor came in a GM parts bag sealed with part number. Very affordable way to setup flex fuel without overpaying for someone else’s emblem on the same sensor that GM uses from the factory for a fraction of the price.

Third failure in 2 years
I have had 3 of these now fail on my sure to low circuit voltage in just over 2 years now. If there is a better quality direct replacement I'll be going with that. It shouldn't matter what vehicle this is in, it's still gas and it ethanol moving through it but for reference 13' STi. This is the same exact one that Cobb puts in their flex fuel kit. Junk it and get a better quality one.

Fixed GMC Sierra P0178 error
Super easy to replace. Start C with a cool engine and catalytic converters. Check online how to release fuel line pressure before removal - and be prepared to catch a lot of fuel.

Essential component of DIY flex fuel system
I coupled this sensor with a home-built arduino setup to measure the ethanol content of the E85 I'm using in my 300ZX. The sensor functions exactly as expected. I haven't been able to compare it to a known test result, but I've seen 9% reported for the E10 fuel in my area, and I'm seeing between 75% and 80% ethanol content in the E85 in my area (the spec allows something like 52%-83% ethanol) so I'm pleased with the results.

As described. No issues.

I guess there is two different ones, this was not the one I needed. Nothing wrong with the part and probably works great, just not the right part for my application
