Easy to DIY
Use YouTube to see how to easily replace these two filters. Honda wanted $130 to replace them. I saved more than $100 buying them and doing it myself in about 5 minutes total time.

Fits perfectly. A fraction of the cost what the dealership would charge. I compared the original to this one and they are basically the same
