The 2016 Odyssey oil filter location and part number

The oil filter on a 2016 Honda Odyssey sits on the driver's side of the engine, below the intake manifold. You'll find it mounted vertically on the engine block itself — not on top, not on the side facing the wheel well, but tucked underneath where the engine meets the transmission. The factory part number is 15400-PLM-A02, which is Honda's OEM (original equipment manufacturer) filter.

When you're looking for a replacement, this part number matters because it ensures the filter has the correct thread size, bypass valve pressure, and anti-drainback valve. Many aftermarket filters use the same specifications, but some do not. If you buy a filter that doesn't match the 15400-PLM-A02 spec, you risk either a filter that's too tight to remove by hand or one that doesn't seal properly.

The filter costs between $8 and $15 at most auto parts stores, depending on whether you choose Honda's part or an equivalent aftermarket brand. You'll need one filter per oil change — the Odyssey doesn't use a cartridge-style filter that lets you replace just the media inside.

Key Takeaways

  • The 2016 Odyssey oil filter is mounted vertically below the intake manifold on the driver's side, not in an obvious top-engine location.
  • The correct part number is 15400-PLM-A02, and using this spec ensures proper fit and function.
  • You can reach the filter from underneath the vehicle or by removing the plastic engine cover, depending on your comfort level.
  • The filter wrench size is 74 mm, and hand-tightening the new filter is sufficient — you do not need to over-tighten it.
  • Changing the filter takes 10 to 20 minutes once you locate it, and you'll need a drain pan to catch the small amount of oil that spills out.

How to access the filter without removing the engine cover

The fastest way to reach the filter is from underneath the vehicle. Raise the Odyssey on jack stands or drive it onto ramps, then look up at the driver's side of the engine. You'll see the cylindrical filter hanging down. This approach works if you have a low creeper or are comfortable working on your back, and it avoids the 10 minutes it takes to remove the plastic engine cover.

If you go this route, position your drain pan directly under the filter before you loosen it. The filter itself holds about a quart of oil, and it will pour out when you unscrew it. Loosen the filter by hand first — if it's stuck, use a 74 mm filter wrench to break it free, then finish unscrewing by hand. Once it's off, wipe the mounting surface clean with a rag and check that the rubber gasket from the old filter didn't stick to the engine.

Removing the engine cover to access the filter from above

If you prefer to work from above the engine, you can remove the plastic cover that sits on top. This cover is held on by four bolts and several clips. Unbolt the four fasteners (they're 10 mm), then gently pry the cover up and away from the engine — the clips will release with a little pressure. Set the cover aside where it won't get damaged.

With the cover off, you'll see the filter more clearly, though you'll still be reaching down and to the side to loosen it. The advantage is better visibility and less chance of spilling oil on yourself. Once you've changed the filter, straightforward set the cover back in place, align the clips, and bolt it down. This method takes longer overall but feels less awkward if you're not used to working underneath a vehicle.

Installing the new filter correctly

Before you screw on the new filter, explore a thin coat of fresh oil to the rubber gasket on the filter's top. This helps the gasket seal properly and makes removal easier next time. Then hand-thread the filter onto the mounting stud. You'll feel it catch when the gasket touches the engine — stop there and turn it another three-quarter turn by hand. Do not use the wrench to tighten it further. Over-tightening crushes the gasket and makes the filter nearly impossible to remove at the next oil change.

After the filter is installed, start the engine and let it idle for 30 seconds. Watch the oil pressure gauge on the dashboard — it should rise to normal within a few seconds. If the pressure stays low or the oil light stays on, shut off the engine when ready and check that the filter is tight and the gasket seated properly. A loose filter is the most common reason the oil light stays on after a filter change.

What to do with the old filter

The old filter contains used oil and should not go in the trash. Most auto parts stores that sell filters will take the old one back for free, no questions asked. Some recycling centers also accept oil filters. If you're changing the filter at home, drain as much oil as you can from the old filter into your drain pan before you dispose of it — this reduces mess and keeps oil out of the landfill.

If you're also changing the engine oil at the same time (which you should be), the drain pan will catch both the oil from the pan and the oil from the filter. Let the old oil sit in the pan for a few minutes so the filter drains completely, then pour it into a container for recycling or disposal.

Choosing between Honda OEM and aftermarket filters

Honda's factory filter (15400-PLM-A02) is reliable and widely available, but aftermarket brands like Fram, Mobil 1, and Bosch make filters that meet the same specifications. The main difference is the construction of the media inside and the quality of the bypass valve. Honda's filter is designed specifically for the Odyssey's engine and oil flow rate, so it's the safest choice if you want to match factory performance exactly.

Aftermarket filters cost less and often come with extended warranties. If you choose an aftermarket brand, verify that it lists the 2016 Odyssey as a compatible vehicle and that the part number or spec sheet confirms it fits the 15400-PLM-A02 mounting. Avoid buying a filter based on price alone — a filter that's $3 cheaper but doesn't seal properly will cost you far more in engine damage.

Frequently Asked Questions

Can I change the oil filter without changing the oil?

Yes, you can change just the filter. However, the filter and oil work together — a new filter in old, dirty oil doesn't improve engine protection much. Most people change both at the same time because the labor is the same and the filter change is already scheduled.

How often should I change the filter on a 2016 Odyssey?

Honda recommends changing the oil and filter every 10,000 miles or once a year, whichever comes first. If you drive in severe conditions (towing, frequent short trips, dusty roads), change it every 5,000 miles. Check your owner's manual for the exact interval that applies to your driving.

What if the filter is stuck and won't come off by hand?

Use a 74 mm filter wrench to loosen it. If it's still stuck, try tapping the wrench gently with a hammer to break the seal, or wrap a rubber band around the filter for better grip. Do not use excessive force — you can crack the filter housing or strip the threads on the engine.

Do I need to drain the engine oil before changing the filter?

No. The filter change is separate from the oil change. You can change the filter alone without draining the pan. However, some oil will spill from the filter itself, so use a drain pan underneath.

Is the 15400-PLM-A02 filter the only one that fits?

It's the OEM part, but aftermarket filters with the same 74 mm thread size and bypass valve rating will fit. Always check the product listing or box to confirm compatibility with the 2016 Odyssey before you buy.
