ACDelco 13577429 GM Original Equipment 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

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

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

Works appropriately and as expected.

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.

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.

Sensor reads 0-209%ethanol

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

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
