Do it!
Size: 5 L
Use it in a 14 Sierra. Get about 7500 miles an oil change going off the oil life monitor but I drive rough and the trucks modded. Pricier than others, but I feel it’s worth it. Truck runs smoother than what was in it.

Perfect Fit, Best Price
Style: 2.0L
The Honda parts sites that appeared in my search results mostly appear to be using the same software for their web-based storefronts and all charging $70+ to $80+ and shipping. These SCREW RHINO filters fit just like the OEM parts, are the same quality and cost about 1/4 of the price. I will not be buying these filters from the dealer parts stores ever again.
