Delphi Corp. announced the expansion of its original equipment engine management offering for the independent aftermarket with the addition of ignition wire sets. Delphi, a leading manufacturer of original equipment wire sets for the automotive industry, brings the same quality parts to their customers in the independent aftermarket. The initial offering includes the 42 highest volume part numbers, covering 20 percent of the vehicles on the road in North America. "This is our latest product introduction in the Engine Management category for the aftermarket in the U.S.," said Lucia Moretti, global marketing director, Delphi Products & Service Solution. "We plan to complete our offering by the third quarter of this year, providing a complete solution for our customers." Based on past model-year history, it is estimated that ignition cable materials can break down over time due to heat and contamination, with average industry replacement at 75,000 miles. Each year, nearly 5 percent of all vehicles on the road will require a replacement wire set. Failed wire sets can cause rough idle, misfire under load, and poor fuel economy.
