AEM’s 30-0302 X-Series 100-300 F/40-150C Digital Gauge combine incredible looks, increased readability and a multitude of new, easy-to-use features! It is a must for users who want highly accurate water, transmission and/or oil or temperature readouts in their high performance vehicle.

NOTE: The 30-0302 comes with a black bezel and black water temperature faceplate. You will need to purchase the optional 30-0302-ACC accessory kit to get the silver bezel, white water, transmission and oil temp faceplates, and black transmission and oil temperature faceplates. Each faceplate is double sided with standard PSI on one side and metric BAR on the other. The calibration for standard or metric display is easily performed using the buttons on the face of the gauge.

EASIER TO READ
Visual improvements include a bright center LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping green LED “needle” lines the edge of the gauge face for quick reference. A 33% overall increase in the gauge face display makes it easier to see at a glance.

EASIER TO MOUNT
Despite the larger display, X-Series Gauges are contained in a standard 2-1/16th-inch (52mm) diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 0.825”, with a cup depth of only 0.200.” This shallow cup depth allows X-Series Digital Gauges to be mounted practically anywhere.

SMARTER INTERFACE
X-Series Digital Gauges include new technological features that make them easier to use. Two buttons on the faceplate deliver programmability for peak/recall, standard or metric center LED readout and sweeping LED needle, and user-selectable threshold warnings. The gauges are AEMnet CAN-bus enabled, so they can be daisy chained together for use with the Infinity ECU, Series 2 EMS, AQ-1 Data Logger, or 3rd party EMS or logger that accepts AEMnet. 0-5V analog outputs are also included for inputting into data loggers and engine management systems.

Perfect fit for 2020 Subaru Outback
Fit my 2020 Subaru Outback perfectly. 5-minute install. Works great. My previous cabin filter was scary to see.

Good, inexpensive replacement filter
I've used these filters for a couple years (four replacements) on my Subaru Crosstrek, and they seem to do the job well, probably as well as the original. I generally remove and clean them every three months, and replace them every six.

Save some money by doing your own cabin filter change! (You won't notice a difference).
So, one day I was getting an oil change at the dealership, and the associate told me that cabin filter was pretty dirty, which I believed because of the places I take the car, and she said that they could change it while they were finishing up the rest of their inspection, since they already had it apart. I asked her "How much?", and then we both had a laugh when she said "$90." I told her I'd take care of it. It took two days for Amazon to get a replacement filter to me, twenty minutes to watch a You Tube video showing how to replace the cabin filter on my car (I watched it twice), and then about twenty-five minutes to replace the filter itself--I keep a messy glove compartment, so a good portion of the time was loading and unloading that nightmare. In the end, under $15 for the filter, maybe 45 minutes to watch and replace, and the cabin filter hasn't been this good since I first bought the car. This replacement version was as good as the OE filter, fit exactly the same, there's no difference in airflow that I can tell, and so far (6 months later), it seems to be holding up pretty well. We'll see what it is like after a year. I did get the oil changed about a week ago, and the technician didn't raise any alarms about the filter, so everything seems to be working. $90 for a new filter? You can do it yourself cheaper.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.
I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.
