Performance II Series instruments have the combined style of European sports car and racing gauges. This performance look has a classic gauge feel without the "in-your-face" look of a racing gauge. Full sweep stepper motors for higher dial resolution and blue LED back lighting at night. Titanium bezels and flat glass add to the high class, OE installed look. Just like always, NVU does not have any logos on the dial so the final result will be a professional, custom look. GENII temperature gauges feature LED backlit dials and pointers with full sweep analog readout for precise readings. Kits include gauge, spin-on back clamp, our hi-match temperature sender (1/8-27 NPT thread) and detailed instructions. Temperature readings range 140F-320F.
