These upgrade units will look different from your stock injectors, but they have the same fitment and flow rate. They are a "plug-and-play" upgrade, no tuning or modifications needed. The upgrade injectors are also OEM Denso fuel injectors, no aftermarket Chinese knockoffs.




The 12-hole nozzle injectors provide better atomization than the standard 4-hole Denso injectors that come stock on these vehicles. These upgrades provide better fuel economy and combustion. They also have the newer coil design which translates to better response time and higher reliability- less failure rate.

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. This is $80 for the advanced flow matching. 

As far as which option is correct, the choice is entirely up to the customer based on their individual needs and budget. Select your preferred flow-match from the drop down menu
