Upgrade your factory high-pressure fuel pump with genuine CorkSport HPFP Internals, designed specifically for Mazda’s turbocharged MZR 2.3 DISI platform.
Developed by CorkSport specifically for Mazda performance applications, these upgraded internals provide significantly increased fuel volume compared with the factory setup, making them a key upgrade for tuned and modified vehicles where the standard pump can become a restriction.
Ideal for:
✅ Mazda 3 MPS / Mazdaspeed 3
✅ Mazda 6 MPS / Mazdaspeed 6
✅ Mazda CX-7 2.3 Turbo
✅ Other compatible MZR 2.3 DISI turbo applications
🚀 Why Upgrade Your HPFP Internals?
As boost, airflow and power increase, the factory high-pressure fuel pump internals can struggle to maintain the fuel volume required under load.
Upgrading the internals helps provide:
🔵 Increased Fuel Volume
Approximately 50% larger than the factory pump internals for increased fuel volume capability.
🟢 Improved Fuel Delivery Under Load
Helps maintain more consistent high-pressure fuel delivery during periods of increased demand.
🟡 More Headroom for Tuned Vehicles
Well suited to vehicles running increased boost, upgraded intake and exhaust components, and performance tuning.
🟠 Improved Fuelling Capability
Helps support the fuel volume required for modified and higher-power applications.
🔴 Precision, Reliability and Efficiency
CorkSport uses precision machining, hardened surfaces and high-strength coatings to provide an accurate, durable fit inside the factory high-pressure fuel pump.
🔧 Designed Specifically for Mazda MZR Engines
Unlike generic fuel pump upgrades, CorkSport developed these internals specifically for Mazda’s MZR DISI Turbo performance platform.
CorkSport spent more than two years researching, developing and testing the design before bringing it to market.
The internals are precision machined, surface treated and coated before final machining to achieve the tight tolerances required for efficient high-pressure fuel delivery.
CorkSport designed the kit specifically for applications including:
✔ Mazda 3 MPS / Mazdaspeed 3
✔ Mazda 6 MPS / Mazdaspeed 6
✔ Mazda CX-7 2.3 Turbo

⚠️ Important
A high-pressure fuel pump upgrade is commonly recommended when tuning the Mazda MZR DISI Turbo platform, particularly when increasing boost, airflow or engine power.
The exact fuel system requirements will depend on the vehicle’s modifications, tune, fuel type and target power level.
Professional installation is recommended if you are not experienced with rebuilding high-pressure fuel pumps.
Correct installation and cleanliness are especially important when working with high-pressure fuel system components.
