I bought these last month and the seller would not exchange them (30+ days policy). They have never been hooked up, fueled up or installed on a running motor. All the paperwork, seals, and stickers are included in the origonal packaging. I am selling these at a considerable loss, and will ship them for free to anywhere in the US. I am asking $310., I have paypal or you could send a check/ money order etc. I need a much larger set as my current build is taking a different direction.

 

high or low impedance?

 

These are the saturated type (12.5 ohm) high impedence for use WITHOUT a resistor box. If you look in on the data sheet you can read all of the specs. These will also work in OBDII with a connector kit and removal of resistor box, no problem. Thanks for your interest

 

Those are seeeexxxxyyyyyy.
