They are good quality, strong, and accurate (even if a bit expensive), but have programmable warning lights and recalls. They even offer a dual gauge with digital Boost and EGT readings in either black or white faces with your choice of red/green or blue backlighting. They come in complete packages (kits) with sensors, owners manual, and wiring.
I have used these gauges in several applications, and definately recommend them if you don't have issues with metric units.
I really like the selection of SPA dual gauges, given the restricted space inside my fairing. While considerably more expensive, the availability of the EGT/BOOST combo with an INTERCOOLER IN/OUT combo is very appealing. Interestingly, one of their Distributors, CDOC, is right up the road from me in Gordonsville, VA.
