Flow Rate Verification Note:
There are several conflicting flow rate specifications published online for Toyota/Denso 23250-75040 fuel injectors, with some sources listing higher numbers. CS Performance specifications are based on in-house flow testing using professional ASNU testing equipment.
 
We tested original stock 23250-75040 injectors side-by-side with these upgraded Denso injectors under the same conditions. Both sets flowed approximately 265 cc/min at 3 bar (43.5 PSI), confirming that these upgrades maintain the correct OEM fuel delivery requirements.
 
These upgrade injectors may look different from your original units but have the same fitment, impedance, and verified flow rate. They are plug-and-play with no tuning or modifications required. These are genuine OEM Denso fuel injectors, not aftermarket replicas.


ADVANCED 1% FLOW MATCHING
The ECU controls your injectors as a set. So if they are imbalanced at all, you will have some cylinders that are flowing slightly rich and some flowing slightly lean. The percentages are how closely the injectors are flow matched to one another. The closer that the injectors flow to one another, the more precise the entire fuel system will be which makes it more efficient. This improved efficiency manifests as better fuel mileage and a smoother engine.
We offer an advanced 1% flow-matching service which also includes documentation of the flow-results for each injector.
As far as which option is correct, the choice is entirely up to the customer based on their individual needs and budget.
