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. GEN II vacuum-boost gauges are fully electronic, no tubing to kink or break! Simply install the compact MAP transducer and wire it up, makes for a very clean installation. Kit includes gauge, spin-on back clamp, VAC/BOOST transducer (1/8-27 thread) and detailed instructions.
