Perfectly fits in place of Bounty/Courier air vents. uses factory vent mounting, slides and clips into place. guage is angled towards the driver for super easy veiwing, suits critical guages that need constant monitoring (like EGT guages) designed to still have proper airflow like a factory vent. suits common 52mm guages. small hole will need to be drilled in the surround to run your power cables (shown in last pic) super clean, OEM look!
