OE Match
OE Match for Porsche
OE Match is a specialist replacement-parts brand developed around Porsche applications, covering routine maintenance, mechanical repairs, restoration and difficult-to-source components for classic and modern models. Design911 selects brands for quality and Porsche fitment, with knowledgeable specialists available to help owners and workshops choose suitable parts.
The OE Match story
OE Match is focused on preserving Porsche vehicles by returning hard-to-find and no-longer-available components to the market. Its purpose is to keep Porsche vehicles maintained, repaired, restored and usable for the future, particularly where original components have become expensive, difficult to source or discontinued.
Supplied catalogue information records over 8000 individual part numbers, more than 11,800 OE cross-references and over 100 new products in engineering, while the wider product programme contains more than 9,000 variants; these figures describe different measures of the range. Continuing development involves researching the parts owners and workshops genuinely need, working with specialist manufacturers, reviewing engineering specifications, assessing samples, testing and approving components before release. From small seals, clips and brackets to major mechanical components, the aim is to prevent a difficult-to-source item from holding up an entire repair or restoration: preserving Porsche, one part at a time.
Why choose OE Match for your Porsche
OE Match is a quality aftermarket and OE-equivalent replacement option developed specifically around Porsche applications rather than adapted from a general aftermarket range. Original references, vehicle fitment information, dimensions, materials and component specifications are used to identify suitable replacements for routine service, age-related wear, larger mechanical repairs and restoration work.
Its research, development and quality-control processes assess material and manufacturing quality, dimensions and specification, OE-reference compatibility, vehicle application, fit and function, supplier samples, product consistency, packaging and presentation. Where appropriate, physical inspection and fitment evaluation form part of final approval, and products must meet the programme's requirements before entering the catalogue.
Coverage includes the Porsche 356, 911, 912, 914, 924, 944 and 928, alongside the 964, 993, Boxster 986, 996, Cayenne, Cayman and 997. This gives owners, enthusiasts, independent specialists and professional workshops a Porsche-focused replacement option alongside Genuine Porsche parts. OE Match is intended to provide correctly specified, OE-equivalent replacements with sensible running costs rather than simply serving as a lower-cost alternative. Design911 selects the brands it carries for quality and fitment and can advise customers on suitable options for maintenance, restoration or upgrades.
