    Our thermostat housing was designed for customers looking for OEM quality parts that function beyond the constraints of factory parameters. The sculpted housing is machined from billet aluminum and then treated to a high-quality black anodized finish. This thermostat housing is adjustable, allowing it to fit many engine and radiator combinations.


     
    For years, customers have asked us to create a reliable solution they could count on. Most available aftermarket solutions offer a sub-par generic thermostat that either leaks, doesn’t function correctly or operates at a temperature outside the OEM specs.Our product covers those bases and more.

    The main housing has a -16 ORB thread which offers flexibility (can rotate 360*) between an OEM style radiator hose or the option to run AN fitting for your radiator. We include a single-threaded port (M18x1.5) in the top section that can be used to add an additional sensor. With an OEM K-Series thermostat (opens at 172.4*F) installed, expect factory functionality and reliability. We also include an OEM-style O-ring to prevent any leaks.

    This kit fits all K20A/Z thermostat bases & K24(A) series bases.

    Fits:

    • K20A/A2/A3/Z1/Z3
      K24A/A1/A2/A4/A8 & K24Z3/Z7

      Not for K20C engines

Well-Made Carbon Cabin FIlter
I love the honeycomb carbon filter on this cabin filter. It looks like it will do an excellent job cleaning the air in my car. It came in a cardboard box and was easy to install and fit my Toyota well. I would have appreciated some arrows on it, like other filters come with, to let me know I was inserting it correctly. I just followed the example of the one already in my car. If you accidentally take that one out first, you may not remember which side goes where. So, my improvement would be arrows on the filter itself. Otherwise, the airflow seems great, it functions well and seems to be a great quality!

Use activated carbon to clean the air naturally!
This is a serious air filter with activated carbon inside of it and I'm here for it. I use little activated carbon bags in my car already as an air freshener because I hate those fake chemical scents from the little trees or from the car wash. The chemicals in those fake scents give me migraines. I absolutely love the idea of putting the active carbon in the cabin air filter itself to clean the air. This fits prefecture in my 2017 toyota prius v. It was just a easy to install as any purge cabin air filter. The hardest part is opening all the parts of the glove box to get the old one out. This filter seems sturdier than my last one and it's a good value for the money.

Perfect fit for 2016 Corolla!
Fit's my 2016 Corolla perfect. Has a sturdy frame. Other name brand ones I have purchased before don't have the sturdy frame and squish up. This comes with tiny fragrant beads on the top part and has a light fresh scent when the air is on. Very happy so far.

Excellent Factory Replacement and a Simple DIY Upgrade
This EPAuto engine air filter is an outstanding, cost-effective replacement for standard factory filters. The build quality is excellent, featuring a durable rubber gasket that creates a tight, reliable seal within the air box to prevent any unfiltered air from bypassing the element. Installing it is a incredibly straightforward task that takes less than five minutes and requires no tools. It offers the exact same performance as premium drugstore or dealership options at a fraction of the cost. Highly recommended for routine vehicle maintenance. Note: Fits perfectly on my Subaru Legacy 2018!
