Honda K Series Oil Filter - 15400-RTA-003
Doing an oil change and need a filter that actually fits? 15400-RTA-003 is the current OEM filter for a
huge chunk of the Honda and Acura lineup, and it's the one you want on the shelf. It threads onto the
block and catches the metal shavings, carbon, and grit that build up in your oil as it cycles through
the engine. Let a filter go too long and it can't keep up anymore, so all that junk starts circulating
through your bearings instead of getting trapped. Throw a fresh one in at every oil change and you're
keeping your oil clean and your engine happy. Grab a single for this oil change, or grab the 6-pack so
you're not back at the parts store every three months.
Same Filter, New Number, New Maker
If you've bought this filter before, here's what changed. Honda discontinued the old 15400-PLM-A01, so
15400-RTA-003 is the number you'll order now. The part that matters most isn't the number, it's who
builds it. The old PLM filter came from Fram, and the RTA filter comes from Mahle, the Mahle Tennex unit
built in Japan that Honda runs on the line. Same threads, same fit, same job, just a different name on
the can. If you've been running 15400-PT7-005, that one's gone too, and RTA-003 is what you'll want
instead. Whatever old number you used to ask for at the counter, this is your filter now, so don't let
the new label throw you off.
What This Little Can Is Actually Doing
Your oil's picking up metal off normal wear, soot from combustion, and dirt that sneaks past the air
filter, and all of that stays suspended in the oil until it hits this filter. Inside, there's a pleated
paper element the oil pushes through. The paper grabs the junk and lets clean oil through to your
bearings, cams, and crank. Once that paper fills up, the bypass valve pops open and your oil starts
flowing around the filter instead of through it. That's the part people don't think about: a clogged
filter doesn't mean no oil, it means unfiltered oil, and you won't see it happening. Swap the filter
every oil change and you never have to think about it.
Why Bother With OEM
You can grab a filter off the shelf at any parts store for half the price, and plenty of them do the
job fine. The catch is the cheap paper inside doesn't catch the small stuff as well, and it breaks down
faster. The OEM filter is built to the same spec Honda designed the engine around, so it catches what it
needs to and lasts the whole interval. Run a cheap filter on a short 3,000-mile interval and you're
probably fine. Push it to 5k or 7k like a lot of people do with synthetic, and that cheap paper can
start breaking down before your next change, or the bypass valve sticks open. Either way, you're running
dirty oil and you don't know it. The OEM filter costs a couple bucks more and it's built to the spec your
car came with from the factory, which is worth it if you're chasing 200k miles and beyond.
One Filter, A Lot Of Old Numbers
Honda's used a handful of different part numbers for this filter over the years, depending on the model
and the year it was built. RTA-003 replaces 15400-P0H-305, 15400-PLC-003, 15400-PLC-004, 15400-PLM-A01,
15400-PT7-005, 15400-RBA-F01, and 15400-RTA-004. They're all the same filter, just labeled differently
for different applications. So if your Honda or Acura originally called for any of those, you don't
need to cross-reference anything. This is your filter.
Buy One Or Stock Up
If you just need one for today, grab a single. If you're doing your own oil changes regularly, the
6-pack's the move. You'll have a filter ready every time without a parts run, and it works out cheaper
per filter too. Got more than one Honda in the driveway, or you're the one your buddies call when they
need an oil change? The 6-pack keeps you stocked and saves you the trip.

Note: Change your oil filter every time you change your oil, don't try to squeeze a second interval out
of one. The paper breaks down and stops catching what it should. When you install it, wipe a little oil
on the gasket, spin it on, and hand-tighten once the gasket touches the block. Don't grab a filter
wrench for this, that's how you crush the gasket and end up with a leak. Snug by hand is all it needs.
Once the oil's in and the filter's on, fire up the engine, let it idle a minute, and look around the
filter for drips. Got a small leak? Shut it off and tighten it a little more, don't crank on it. Still
leaking after that? Check the gasket for damage or grit on the sealing surface, then reseat it. As for
intervals, match it to how you drive: city and short trips, 5k is a safe bet; mostly highway with good
synthetic, 7k to 8k works fine. Just don't stretch it past 10k, even on synthetic, the oil breaks down
and the filter fills up either way. Keep up on both and your engine will thank you for it.
