The intake manifold is a critical engine component that sits between the throttle body and the engine's cylinder head(s). Its primary functions include:

• Air Distribution: Evenly distributes the incoming air charge across all cylinders to ensure balanced combustion in each cylinder
• Air-Fuel Mixing: In port-injected engines, the manifold provides the channel through which fuel injectors deliver fuel into the airstream before it enters the combustion chamber
• Vacuum Source: Provides manifold vacuum used by brake boosters, PCV systems, EGR valves, and various sensors and actuators
• Idle Quality: A sealed manifold maintains correct idle speed and throttle response — any vacuum leak directly affects idle quality and fuel trim
• Plenum Chamber: The plenum section smooths airflow pulses from the throttle body before distributing air to individual intake runners

On Mazda's Skyactiv engines, the intake manifold is also closely integrated with the engine's high-compression combustion strategy, making correct airflow distribution especially important for achieving the intended fuel economy and performance targets.

Common symptoms of a failing or damaged intake manifold on a Mazda Skyactiv engine include:

• Rough or unstable idle — particularly noticeable when the engine is warm
• Check Engine Light illuminated — often with lean mixture codes (P0171, P0174) caused by vacuum leaks
• Reduced engine power or poor throttle response
• Increased fuel consumption due to incorrect air-fuel ratio management
• Hissing or whistling sounds from the engine bay under load or at idle — a classic sign of a vacuum leak
• Engine misfires on one or more cylinders caused by unequal air distribution
• Coolant leak near the intake manifold gasket area (where applicable)
• Visible cracking, warping, or physical damage to the manifold body

If any of these symptoms are present, have the intake manifold and associated gaskets inspected by a qualified mechanic before replacing components.

Self-installation is not recommended. Professional installation by a qualified mechanic is strongly recommended for the following reasons:

• Torque Sequencing: Intake manifold bolts must be torqued to specification in the correct sequence to ensure even gasket compression and prevent warping or leaks
• Vacuum Line Management: The Mazda Skyactiv intake manifold connects to multiple vacuum lines, sensors, and actuators — all must be correctly reconnected and inspected for condition
• Leak Testing: After installation, a vacuum and smoke leak test is recommended to confirm full seal integrity before returning the vehicle to service
• Throttle Body Cleaning: Intake manifold removal is an ideal opportunity to clean the throttle body — a mechanic will be best placed to carry this out
• Warranty Activation: Professional installation is required to validate the 12-Month Worry-Free Warranty

Note: Installation instructions are not included with this product.

This intake manifold assembly is compatible with Mazda 3, Mazda 6, and Mazda CX-5 models fitted with the 2.5L Skyactiv engine between 2014 and 2020. The 2.5L Skyactiv-G engine architecture is shared across these three platforms, which allows a single manifold to serve all three models within this year range.

However, we always recommend verifying fitment by:

• Matching the OE Part Numbers (PY0113100A, PY01-13-100A, PY01-13-100) against those on your original manifold
• Providing your VIN to our team for confirmation before ordering

Minor production changes or regional specification differences can occasionally affect part compatibility within a model year range.

Mazda's Skyactiv-G engine is designed around an exceptionally high compression ratio (13:1 or 14:1 depending on variant) — higher than almost any other production petrol engine. This high-compression strategy requires precise, uniform air delivery to all cylinders to achieve the intended combustion efficiency.

The intake manifold plays a direct role in fuel economy on these engines because:

• Uniform Air Charge: Equal air distribution ensures every cylinder fires with the same air-fuel ratio, maximising the efficiency of each combustion event
• Plenum Volume: The manifold's plenum and runner dimensions are tuned for the Skyactiv engine's specific rpm range and valve timing to optimise torque and efficiency
• Leak Prevention: Any vacuum leak in the manifold introduces unmetered air into the engine, causing the ECM to miscalculate fuelling — directly worsening fuel consumption and increasing emissions

A correctly fitted, leak-free intake manifold is essential to realising the full fuel economy benefit Mazda's Skyactiv technology is designed to deliver.

Yes — replacing the intake manifold gaskets at the same time as the manifold assembly is strongly recommended. Since the manifold must be fully removed to complete this job, fitting new gaskets adds minimal additional cost while offering several important benefits:

• Guaranteed Seal: New gaskets ensure a fresh, reliable seal against both the cylinder head and throttle body mating faces
• Avoids Repeat Labour: Old compressed gaskets are more likely to leak after reinstallation — replacing them now avoids having to remove the manifold again in the short term
• Prevents Vacuum Leaks: Even a minor intake gasket leak can cause rough idle, poor fuel economy, and persistent lean fault codes
• Cost-Effective: Gaskets are inexpensive relative to the labour cost already being incurred for the manifold replacement

Ask your mechanic to inspect all vacuum lines, PCV hoses, and throttle body connections while the manifold is removed, as these components are conveniently accessible during this service.

This product includes a 12-Month Worry-Free Warranty under the following terms:

• Eligibility: Valid for all items fitted by a fully qualified mechanic
• Verification: Proof of installation on official business letterhead from your mechanic may be requested for warranty verification
• Coverage: Covers manufacturing and material defects only — damage caused by incorrect installation, failure to follow installation best practices, or use of incorrect fitment is not covered

D2P Autoparts stands behind the durability and quality of its products. If you experience any product-related issue within the warranty period, please contact us with your proof of professional installation.

This is a high-quality aftermarket replacement part manufactured by D2P Autoparts and engineered to meet or exceed Mazda's OEM (Original Equipment Manufacturer) specifications. It is 100% brand new and designed as a direct replacement for the factory intake manifold on Mazda 3, 6, and CX-5 models with the 2.5L Skyactiv engine.

It delivers the same fit, sealing performance, airflow characteristics, and dimensional accuracy as the original Mazda component — at a more competitive price point than a Mazda genuine part, without compromising on quality or long-term reliability.

Replacing a cracked, warped, or leaking intake manifold with a new direct-fit unit will restore the engine to its factory performance specification — rather than adding performance beyond the original design. The key benefits of replacing a worn or damaged manifold include:

• Restored Idle Quality: Eliminates rough, unstable, or high idle caused by vacuum leaks
• Corrected Fuel Trims: Removes unmetered air that causes the ECM to run lean corrections, restoring factory fuel economy figures
• Resolved Fault Codes: Clears persistent lean mixture or MAF-related fault codes caused by manifold leaks
• Even Cylinder Distribution: Restores equal air charge to all cylinders, recovering any lost power from cylinder imbalance
• Throttle Response: Correct plenum sealing restores crisp, predictable throttle response

If your Mazda was running correctly before manifold failure, a quality direct replacement will return it to that standard reliably.

To confirm 100% compatibility before purchasing, follow these steps:

• Check Make, Model & Year: Confirm your vehicle is a Mazda 3, Mazda 6, or Mazda CX-5 between 2014 and 2020
• Verify Engine Size: Confirm your vehicle is fitted with the 2.5L Skyactiv engine — not the 2.0L or any other Skyactiv variant
• Match OE Part Numbers: Compare the part numbers in our specifications (PY0113100A, PY01-13-100A, PY01-13-100) against the number stamped or labelled on your original intake manifold
• Contact Us with Your VIN: Provide your Vehicle Identification Number and our team will confirm exact fitment before you place your order

Checking the OE part number on your existing factory unit is the most reliable method to guarantee correct fitment for your specific Mazda.
