I was mainly looking for comparison with the OEM filters and Ridge17 gave the best feedback rather than just say "it worked for me". The reason being is the last time I bought an engine air filter at the local parts store, it was "paper" element which was decades ago. It literarly looked like pleated paper. Since then, I've been using k&n and never looked back. Our '17 Pilot needed a new engine air filter and to my surprise, it didn't resemble anything like the last one I bought decades ago LOL. I wanted to know what you guys are using, the cost, and maybe doing away with k&n. Don't get me wrong, I do appreciate the comments and suggestions. With that said, after reading the description of the cabin air filter that you and Smufguy suggested, I will get them for my '19 RL.
As far as synthetic gasoline engine oil, there was an article that I read comparing the "top" synthetic oils. I stopped using the Walmart brand SuperTech after that. Our local Navy exchange has the cheapest gas which I've been putting in my vehicles since 1995. Apparently, I want to avoid that with our RLs as well.
