surrey86 352 Report post Posted June 15, 2019 I'm selling my P3 cars vent gauge. Excellent condition, full working order. It is one of these - https://www.fensport.co.uk/parts/subaru/brz/zc6/gauges/gt86-p3-gauge-pre-installed-in-vent/ It is the version that is pre-installed in a vent, so no messing about. You just unclip the silver trim ring and outer ring off your existing vent and clip it around this. The plug goes into the OBD port. The extra wires are if you want to plumb in additional sensors, but I've never touched them. £210 inc. postage, or £200 picked up. (Caterham, Surrey) I'll be at a few meets coming up - Bromley Pageant of motoring, Japanese Auto Matsuri, and the Japanese Sprint series at Kendrew. Share this post Link to post Share on other sites
