Our expertise is built around the products in the live catalogue: 120+ sensor and TPMS SKUs, 68 ignition coil SKUs, and a focused range of transmission components and precision DC motors.
Product Knowledge That Matches the Catalogue
Sensors
Ride-height, oil-pressure, temperature and transmission sensors checked by OE number, connector, output type and vehicle application.
Ignition Coils
Coil-on-plug and related ignition coverage researched by OE reference, engine platform and electrical design.
TPMS
315MHz and 433MHz sensors matched by vehicle market, radio protocol, valve specification and relearn requirements.
Precision DC Motors
A focused range for headlight leveling, mirror movement, locking and charge-port actuation, specified by voltage, torque, RPM and dimensions.
How We Verify Fitment
We start with the OE number, then compare vehicle application, connector geometry, electrical or radio specification, and the physical mounting points. Where catalogue data is ambiguous, we ask for the VIN, original-part label or installation photos before recommending a replacement.
From German Luxury Vehicles to Broader Global Coverage
Longwei developed its early aftermarket experience around Audi, Volkswagen, Mercedes-Benz and other German platforms. That technical discipline now supports expanding product coverage for American, Japanese, Korean and Chinese vehicles without presenting European specialization as a market limit.
Support for Workshops & Distributors
Independent workshops can send one difficult OE-reference question; distributors can send a multi-line RFQ. We return the closest verified matches, identify uncertain applications clearly, and avoid substituting a part based on appearance alone.
