When the OEM partner first approached our team, the brief was straightforward: deliver a iridium spark plug line that could stand up to local driving conditions without breaking the distributor's margin model.

The local aftermarket was dominated by a long-standing Japanese brand, and stock-outs during peak summer driving season damaged loyalty. Fleet operators reported premature wear and warranty disputes that were damaging the distributor's reputation.

Our engineering team proposed a two-phase validation: a 90-day field trial with 120 units installed on partner fleets, followed by a controlled regional rollout with co-branded packaging and a 18-month warranty backed by our Guangzhou technical office.

Within the first six months, warranty claims dropped by 62% across the trial fleet. Year-on-year reorder volume reached consistent reorder volume every six weeks, and the distributor has since expanded into filters and service-parts bundles on the same supply agreement.

We are now scoping the next phase: extending the program to an on-line B2B ordering portal for workshop customers, with on-site training for distributor technicians and a shared forecast rolling twelve months ahead.
