Honda K20C1 Engine Cover 12500-5BF-A03

Honda K20C1 Engine Cover - Civic Type R (2017-2021 FK8, 2023+ FL5)

This is the genuine OEM Honda engine cover for the Civic Type R (part 12500-5BF-A03), the molded cover with the signature Type R styling that sits over the valve cover. It's a direct factory replacement for a worn, damaged, or missing cover, or the finishing piece for a K20C1 swap. And because it's the real Type R cover, it's also the popular way for Accord 2.0T and RDX owners to bring the Type R look to their own engine bay.

Also Fits The Accord 2.0T And RDX (K20C4)

This is the detail a lot of buyers are here for, so it's worth explaining properly.

The Type R's K20C1 and the K20C4 in the Accord 2.0T and RDX are closely related engines, which means this genuine Type R cover physically fits the K20C4 as well. For an Accord or RDX owner, that's the way to dress the engine bay with an actual Honda Type R part rather than an aftermarket lookalike.

Fits for this install: 2018-2022 Honda Accord 2.0T and 2019-2025 Acura RDX 2.0T (K20C4).

What The Accord/RDX Install Involves

Know this before you start, because it's more than a straight bolt-on for these cars.

To fit the Type R cover on the Accord or RDX, you'll need to remove the factory studs and the small factory cover first, then mount the Type R cover in their place. It's not difficult, but it's a few steps rather than a simple swap, so plan for it rather than being caught out.

Once the factory studs and small cover are off, the Type R cover secures with four Honda retaining bolts (part 90014-R40-A00). You'll want four of those on hand, so order them alongside the cover, since the install won't be complete without them.

What It Is

Straightforward, so nobody's surprised by what arrives.

This is the molded plastic engine cover with the factory Type R styling, finished to sit over the valve cover and give the bay a clean, complete look. It's the genuine Honda piece, so the fit, the texture, and the styling are correct, not an approximation.

Note that this is the cover only. On the Type R it does not include the mounting studs that thread into the valve cover, so if yours are damaged or missing you'll need those separately. On the Accord and RDX, you'll need the four retaining bolts noted above.

Why People Buy This Cover

A few different reasons, all valid.

Replacement: engine covers crack, warp from heat, or go missing over the years. A genuine replacement puts the bay back to factory.

Swap completion: if you've done a K20C1 swap, this is the cover that finishes the engine and makes it look like it belongs.

The Type R look: for Accord 2.0T and RDX owners, it's an easy, genuine-Honda way to give the engine bay the Type R appearance using the actual part rather than a copy.
