The best STRI gauge in this collection depends on what you need to watch: the Xline V2 oil temperature gauge is the pick for engine health on a hard-driven car, the exhaust temperature gauge suits turbocharged builds, and the voltmeter gauges cover charging-system monitoring. Every gauge here is an STRI Xline V2 in 52mm or 60mm with a clear or smoked lens and white display, and all are listed as universal fit.
An auxiliary gauge shows one reading the factory cluster either hides or reports only as a warning light, so by the time a stock car tells you something is wrong, the gauge car often knew minutes earlier. Oil temperature tells you when the engine is warm enough for full load; exhaust temperature is a tuning reference on turbo cars; a voltmeter flags a weak battery or alternator early.
STRI is a gauges-only brand in this catalogue, and the Xline V2 range here is consistent by design: the same styling across functions means a matched set looks factory-intentional rather than pieced together. The voltmeter alone comes in three versions — the 52mm clear lens voltmeter, a 52mm smoked lens version, and a 60mm clear lens version — so diameter and lens are the first choices, function is the second.
For engine-focused monitoring, the Xline V2 52mm oil temperature gauge and the Xline V2 60mm exhaust temperature gauge are the two picks in this collection, both with clear lenses and white displays. Temperature gauges need a sender in the oil or exhaust stream, so plan the sensor fitting as part of the install rather than treating the gauge as a standalone part.
STRI sits in a deep gauges category at JDMuscle: Auto Meter is the long-established American gauge maker with a much wider catalogue of styles and functions, while AEM is known for wideband air-fuel gauges and digital displays used in tuning. Browse the wider interior trim and accessories range for pods and mounting options, and read what to monitor on your WRX for which readings matter most on a turbo Subaru.
What is the difference between 52mm and 60mm gauges?
It is the diameter of the gauge body, and it decides which pod or mounting hole the gauge fits. This collection lists the voltmeter in both sizes; measure your pod or dash opening first, because the two sizes are not interchangeable.
Clear lens or smoked lens — which should I choose?
Both versions in this collection use a white display; the difference is the lens finish and how the face looks when the car is off. It is a styling choice rather than a functional one, so match the rest of your interior plan.
Are STRI gauges a universal fit?
Yes, every gauge here is listed as universal, which means the gauge itself is not car-specific — but the sender, wiring, and mounting solution still have to suit your car. Budget for a pod or mount and the correct sensor fitting for temperature gauges.
Which gauge should a turbo car run first?
Of the functions in this collection, oil temperature is the most useful first gauge for a hard-driven turbo car, with exhaust temperature second. A voltmeter covers the charging system the others do not watch.
