IE TrueFlex Sensor Harness For MQB Engines | Fits VW MK7 & Audi 8V Engines

The HP and fuel savings are amazing!!

I am no mechanic at all and I was able to install this kit myself. I decided to go flex fuel when Premium went over $4, and boy was it a good choice. I would strongly encourage you to practice positive self talk along some patience when it comes to installing the new pin and fuse. That was probably the hardest part but really worth all the effort! I love IE products for how they right just right all the time as well as the perfect build quality!

TrueFlex Sensor

Sweet kit, great installation instructions and a fairly easy install. Took me an hour tops. The pinning of the ecu signal wire definitely the most difficult part but honestly not hard. Worth the time for sure with the TrueFlex tune installed. Takes longer for the ethanol content to reach it's new level after filling up than I expected but not an issue. Usaully within 5 to 10 miles it levels out after filling up :)

Worth it

Do it, the only scary part is the pin addition on the ECU, but just follow instructions and will be fine. Great addition to the stage one HPFP high torque, it feels real good. And California E85 at 2.50 is nice. Just had to grind off a bit of the intake manifold fins to make the sensor fit flat and snap on the stock clamps
