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!

tedious process

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 :)
