i had these gauges imported from the usa, they cost me £200, now ive had them for about 3 years, i place them in my car but never plumbed them in, they were in my car for about 2 weeks and then i took them out and popped them in the loft, the pics aint to good but these are as good as new, there really good quality, they light up either blue or green as i have 2 different colour bulbs they do work as i heated the stats up with a blowlamp to check,, there 52mm, there really good quality!
ill post these for £80? or offers close to
these are direct plumbed in so no control unit needed
