Link ECU G4X StormX

Advanced tuning features at an affordable price.  

The Link G4X StormX ECU is the latest version of our trusty, mid-sized ECU. With eight injector and eight ignition drives, it allows sequential injection and direct spark on engines with up to eight cylinders or four rotors. 

The StormX has all the upgrades of the AtomX and MonsoonX but offers more advanced tuning features like a built in Trigger Oscilloscope, Stepper Motor Idle Control, Rotary Oil Metering Pump Control, Onboard Knock Control, Open and Closed Loop Boost Control plus most Motorsport features including Full Gear Shift Control, Antilag and Launch Control. 

The StormX has expanded data logging and is more responsive with a higher bandwidth than its G4+ Storm predecessor. G4X features 512 megabytes of logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100 kSamples/sec.

It also features 8 x faster communications speed, allowing you to download logs 8 x faster and pushes all the logging quickly up to a new and improved PC Link – available for download below in the features tab.

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.
