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.
