The K&N 33-5020 is a reusable, washable panel air filter for the right-side airbox of the 2015-2016 Hyundai Genesis Sedan with the 5.0L Tau GDI V8. The Genesis V8 runs two airboxes, so this filter replaces only the right-hand disposable element, and the manufacturer pairs it with the 33-5021 for the left side. Its cotton gauze media arrives pre-oiled and is meant to be cleaned and re-oiled instead of discarded, which is the main reason to pay more than a basic paper replacement. K&N describes the design as high-flow while still filtering enough to protect the engine, and the filter is covered by K&N's limited warranty.
Installation is a straightforward drop-in job for a DIY owner: the filter is shaped to the factory airbox and does not require modification. It cross-references Hyundai OE number 28128-B1000, so owners searching for a K&N 33-5020 2015 Genesis 5.0 right airbox filter, a washable Tau V8 intake filter, or a reusable Genesis sedan replacement panel will find it fits the stock housing. Plan on cleaning and re-oiling it every service interval rather than replacing it, and use K&N filter oil in a light, even coat to avoid contaminating the mass airflow sensor downstream.
No. The manufacturer lists the 33-5020 for the right-side airbox only. The left-side filter is the K&N 33-5021.
The manufacturer cross-references the 33-5020 to Hyundai part number 28128-B1000.
The manufacturer specifies a re-oiling amount of 1.21 oz (36 ml).
K&N's product listing describes a No-Hassle Lifetime Limited warranty, while some of K&N's other materials reference a Million Mile Limited Warranty. Details vary across these materials, so confirm the current terms with the manufacturer before relying on either.
Replacing this filter is a basic maintenance task. Open the right-side airbox, note how the old element sits, lift it out, and drop the K&N in with the same orientation before closing the housing. Check the airbox for clips or fasteners before you start so you do not force anything. When cleaning, use a K&N-approved cleaner, let the element dry fully, and apply a light, even coat of filter oil. Avoid over-oiling, since excess oil can migrate into the intake and foul the mass airflow sensor.
