Troy, MI — When Delphi introduced its aftermarket SP compressors earlier this year, the product line was developed based on usage by major OEMs worldwide. Delphi has been practicing the same stringent validation, testing and manufacturing processes for every part it produces.

All parts released for the aftermarket undergo rigorous product development processes including Production Part Verification (PPV) and Production Part Approval Process (PPAP).
The purpose of PPV is to confirm the part being produced performs exactly as the prototype was designed; and the purpose of the PPAP is to ensure every part meets all of the requirements defined in the engineering samples. What’s more, any plant manufacturing a Delphi part must adhere to all of Delphi’s manufacturing standards to include performance, noise and durability testing.

Delphi’s SP compressors were tested to Delphi’s durability requirements — which, in some cases, are more stringent than those of the global OEMs it serves — and met the demands of completing the test without exhibiting excessive wear. Like all products in Delphi’s aftermarket thermal line, the compressors are designed to last a minimum of 50,000 miles. The SP compressors also meet the designated performance requirements and exceed the Delphi requirement that calls for a noise differential of less than 3 dB. In addition, Delphi’s SP compressors underwent vehicle fit and leak testing to ensure Delphi-caliber quality.

Delphi’s new compressors fit popular late-model domestic and import applications, with coverage for more than 13 million vehicles.
