    Rated 3 out of 5 by from It is what it is It is advertised as a 1.0 ohm resister but actual resistance is 1.8 ohms (at 70degrees).

    Rated 1 out of 5 by from Wrong Ohm mesurements I bought 2 of these for my RoadRunner. They were supposed to be 1 ohm resistance, but when I measure them with my ohm Meter, with alligator clips, no human touch to change resistance, they both measured out at 1.5 Ohm. They were only $9.99 Each, but JEGS charges the $11 return for parts, so it's not worth sending back. I'll just throw them away because they are useless as a spare. I bought a MSD resistor that was twice the price, but the 0.8 Ohms rating on that resistor, measured out to 0.8 Ohms correctly.
