Delphi Auto Parts has added ignition coils for 7.5 million Nissan, Infiniti, and Honda vehicles. The company says the new coils have undergone stringent OE endurance testing and meet all OE specs for performance, durability and reliability. They feature precise spark timing response for increased fuel economy and faster crank to run while also producing efficient and continuous energy to maintain drivability. Delphi ignition coils provide accurate electrical energy to create a voltage potential at the spark plug, providing for superior engine performance that adjusts to driving and environment conditions. Delphi’s ignition technology includes world-leading magnetic design and modeling capability for highly efficient power transfer, less internal heating and more spark energy with lower input power.
