J1YL2C Engine & Cabin Air Filter for Mazda CX-5, Mazda3 & Mazda6 (Non‑Turbo, 2013–2023) OEM fit, pleated media

J1YL2C Engine & Cabin Air Filter is a direct-fit replacement air filter designed to restore airflow and cabin filtration for specified Mazda 3, Mazda 6 and CX-5 models.

This combined engine and cabin filter from J1YL2C is built to match the original equipment fit and function for many Mazda model years, replacing OEM numbers such as CPJ6X, CP11811 and KD45-61-J6X. Manufactured to the same footprint and mounting dimensions, it slips into the factory housing and helps maintain engine breathing and passenger cabin air quality. The filter is offered as a routine service item with a recommended change interval and straightforward installation that most DIYers can handle in under ten minutes.

Which vehicles and part numbers is this filter compatible with?

This J1YL2C unit is compatible with Mazda 3 (2014–2018), Mazda 6 (2014–2021) and CX-5 (2013–2023) non-turbo models. It replaces a long list of OEM and aftermarket references so you can match it to your existing part number before purchase.

• Compatible models: Mazda 3 (2014–2018), Mazda 6 (2014–2021), CX-5 (2013–2023) — non-turbo only.
• Replaces: CPJ6X, CP11811, KD45-61-J6X, KD45-61-J6X9U, KR11-61-J6X and many cross-references.
• Also cross-references: MP11-1K-D45, CA11259, AF5211, PCA11259 and more for easy fit confirmation.

How easy is it to install and how often should I replace it?

Installation is intentionally simple: the filter is a direct-fit part that requires no specialty tools, and most installations take about 5–8 minutes. Routine replacement keeps airflow and filtration performing as intended, and the manufacturer recommends changing the filter every 12 months or every 12,000 miles, whichever comes first.

• Estimated install time: 5–8 minutes for most users.
• Tools needed: basic hand tools only (if any) — typically none required.
• Replacement interval: approximately 12 months or 12,000 miles.

What performance and fit characteristics should I expect?

The J1YL2C filter is made to replicate OEM dimensions so it seals correctly and prevents bypass. It provides consistent airflow for engine efficiency while helping reduce particulates and debris from entering the cabin or engine intake. Materials and pleat design aim to balance filtration effectiveness with low airflow restriction.

• OEM-form fit for proper sealing and easy swap-in replacement.
• Pleated media for a balance of filtration and airflow.
• Durable frame to hold shape during installation and use.

Can I confirm fit for my car before ordering?

Yes — verify compatibility by checking your vehicle’s year, make and model against the compatibility list and OEM cross-references. Using the vehicle selector (for example, a vendor’s 'My Garage' tool) or matching your current filter’s part number to the listed replacements reduces the chance of ordering the wrong item.

• Check vehicle years and non-turbo engine requirement before buying.
• Match existing part number to the provided cross-reference list.
• Use vendor fitment tools or VIN lookup where available for confirmation.
