Serfac delivers comprehensive ignition and engine management solutions
As vehicle engine management systems become increasingly sophisticated, access to high-quality ignition, sensor and engine management components is more important than ever. Serfac Limited supports the Irish automotive aftermarket with a comprehensive portfolio covering spark plugs, glow plugs, sensors and ignition components from some of the industry’s leading global manufacturers.
Bringing together established brands including Denso, BERU, Vitesco Technologies, Hoffer Products and Metzger, Serfac provides motor factors with access to an extensive range of products for petrol and diesel applications across the Irish vehicle parc.
Denso – OE expertise in spark plug technology
Denso is one of the world’s leading automotive technology manufacturers and has a long-established reputation for ignition technology in both the OE and independent aftermarket sectors. Serfac offers an extensive selection of DENSO spark plugs, covering conventional nickel, platinum and iridium technologies. DENSO’s advanced spark plug designs are engineered to deliver reliable ignition performance, efficient combustion and long service life across a broad range of vehicle applications.
BERU – a specialist name in ignition and cold-start technology
BERU, a BorgWarner brand, brings extensive OE heritage to Serfac’s ignition offering. The brand is particularly well known for its expertise in glow plugs, ignition coils and ignition technology, providing aftermarket solutions developed to meet the demands of modern engine systems. BERU glow plugs are designed for rapid heat-up and dependable starting performance, while its ignition components provide accurate and reliable delivery of the high voltage required by modern petrol engines.
For workshops diagnosing starting difficulties, misfires or ignition-related performance problems, using quality components is particularly important. Increasingly complex engine management systems mean that a fault in one part of the ignition system can affect performance, fuel consumption, emissions and drivability.

Vitesco – advanced engine management technology
Serfac has also strengthened its engine management offering with an expanded range of Vitesco components, bringing advanced OE expertise to the independent aftermarket. Now part of Schaeffler, Vitesco has a strong heritage in powertrain and engine management technology. The range available through Serfac includes important components such as NOx sensors and fuel injectors, supporting workshops servicing increasingly sophisticated petrol and diesel powertrains.
NOx sensors play a critical role in modern emissions management systems, continuously monitoring nitrogen oxide levels and providing information to the vehicle’s engine and emissions control systems. With increasingly complex exhaust aftertreatment systems, accurate sensor operation is essential for correct system performance and emissions control.
Hoffer Products – extensive sensor and engine management coverage
Hoffer Products further strengthens Serfac’s engine management programme with an extensive range of electrical and electronic replacement components. The brand offers broad coverage across numerous sensor and engine management categories, providing solutions for a wide variety of European and Asian vehicle applications. From sensors monitoring engine operating conditions to components responsible for fuel delivery and emissions management, the range helps workshops address an increasingly diverse mix of electronic and engine management repairs.
Metzger – comprehensive electronic component coverage
Completing Serfac’s offering is Metzger, another established aftermarket specialist with particularly strong coverage in electronic and engine management components. The Metzger portfolio includes an extensive selection of sensors, switches, ignition and engine management components, providing additional coverage for both established and newer vehicle applications. This breadth is increasingly valuable as workshops encounter a growing number of electronic systems and vehicle-specific component requirements.
The growing complexity of vehicle electronics has changed the nature of many routine repairs. A warning light, starting problem, loss of power or increased fuel consumption can potentially originate from a wide range of sensors, ignition or emissions-related components. Accurate diagnosis is therefore essential before components are replaced. Once the source of the fault has been identified, component quality and correct application become equally important.
By combining leading OE and aftermarket brands with extensive application coverage, strong stock availability and knowledgeable technical support, Serfac provides motor factors with a comprehensive solution for today’s ignition and engine management requirements.
