The DSX Tuning flex fuel kit is the original plug and play solution to adding flex fuel on Gen IV/Gen V GM V8 vehicles. Use these kits to add the ability to run anywhere from straight gasoline to straight ethanol as well as reveal the true power potential of your setup.

This kit uses:
- Genuine GM Flex Fuel Sensor
- Plumbing kit made of corrosion resistant materials to ease installation
- Plug and Play wiring harness made with OEM connectors and terminals crimped with OEM tooling

Feel that flex without feeling that rubbery texture.
Size: 36W x 30L, Color: Black
These fit great! The texture isn't wuite like denim, more like a soft tablecloth, but that's quite alright. They have a flex that I need. Sometimes with "slim fit" stretch jeans, I feel a bit restrained in my thighs, this time, instead of ordering my usual size, I went up a notch. I can just wear a belt if I need to. I can fully articulate my legs in this set, in the stretchiness doesn't feel like weird rubbery velvet. They look good, they feel good. I imagine they'll last a bit longer than some of my other stretch jeans that had spandex or whatever in them.

Good work pants
Not too bad, but the material is thin. The fit is perfect, exactly what I ordered. I will use them for errands and working around the house.
