This is only the second time I’ve changed my oil in 4 years (once a year; only 13K at this point) so I’m still learning some things. My dealer did the first 2 and the filter was stuck on pretty good last year when I changed it for the first time. I finally got it off using a strap wrench but felt a cap style wrench would do better.
I’m also somewhat frugal so I balked at spending $30-$35 for the Honda wrench. I measured the flats on the 15400-PLM-A01 at exactly 64mm. After reading a lot of reviews including some saying the Honda wrench (which is listed at 65mm) could slip on an overly tightened filter, I decided to get a 64mm wrench which commonly fits Toyota vehicles.
I bought the Assenmacher Speciality Tools TOY 640 wrench. It’s available on eBay for around $20 w/free shipping. Fits the A01 filter perfectly. In fact may be a smidge loose but also allows you to slip a baggie over the filter and still have it fit.
Its made from cast aluminum right here in the USA which is a nice bonus. You’ll need at open ended 15/16“ or 24mm wrench. I barely applied any pressure against the wrench (my 15/16 is pretty big and allows a lot of leverage) and the filter started turning. I know I probably didn’t need to get this wrench since I didn’t over tighten the filter last year but it’s nice to have the right tools for the job.
Figured this info could also help those of you with overly tightened filters since it seems like a robust little wrench and allows a lot of leverage. Just remember to try and remove filter first before you drain the oil in case it’s stuck. That way you can order this wrench and still drive the truck while you wait on it (learned that little trick right here 😀).
I also ordered a Motivx Tools oil funnel (with adapter), part no. MX230B2 but haven't received it yet. I’ll edit this post once I get it to reflect whether you need the adapter to fit the Ridgeline (only found a couple reviews but seems you will need one). One of the other members here bought the Assennmacher funnel but they think very highly of them and, with the adapter, would have been almost $50. I got this one for $17.95 from eBay.
Edit: You definitely need the angled adapter with the oil funnel. The funnel alone is too long and hits the top of the radiator shroud. The adapter doesn’t really screw in; it has a big ribbed gasket that gets pushed down into the hole. Fits pretty well, won’t know how it works until next year.

. I don't remove any clips at all - the filter is accessible enough from the left hand side of the plastic cover without removing it.
