No new historical original-equipment supplier relationship is asserted.

Bosch 0 280 160 542 is documented as a matching replacement, not as proof that Bosch supplied Porsche production. Confirm rated pressure, engine and fuel-system diagnosis before ordering; fuel-system work must follow the workshop depressurisation and leak-test procedure.

MAHLE's catalogue and the retailer cross-reference establish LX 459 as a replacement for both Porsche references, but the checked evidence does not establish MAHLE as Porsche's factory supplier for this filter.

MAHLE's catalogue establishes the exact LX 459 cross-reference, but the checked sources do not establish MAHLE as Porsche's factory supplier for this part.

The Hamburg-Technic replacement uses revision 993 110 337 51 and explicitly cross-references PET revision 993 110 337 50. Confirm the supersession, hose ports, electrical connector and turbo application before ordering. The alternative-manufacturer listing is not evidence that Hamburg-Technic supplied Porsche original production.

Confirm condition before purchase; do not treat it as an unrestricted new replacement for all 993 engines.

Partworks item 14000 is the seller's catalogue identifier. The checked page does not publish JP - Dansk's own reference, so no maker or original-equipment reference is inferred.

The stainless alternative is sold individually and one is required per silencer. Classic Line/JP Group is documented only as the replacement manufacturer, not as Porsche's original supplier.

The Genuine page recommends six sealing rings per engine; confirm exhaust configuration and quantity before ordering.

The Genuine Porsche offer is the individual right tail pipe; the performance alternative is a left/right polished-stainless kit for the C4S. JP Group's cross-reference does not establish factory-supplier status.

The Albert Motorsport product is a left/right pair; this record covers the right-side factory reference named in its SKU.

The Genuine Porsche option is used and requires inspection or refurbishment before installation. The alternative removes the catalyst; verify emissions, noise and road-use legality for the destination jurisdiction before purchase.

No new historical original-equipment supplier relationship is asserted. Weight applies to the left-and-right bypass pipe set. FVD explicitly names JP Group / Dansk as manufacturer. This is a racing-only catalyst bypass, not a road-approved catalytic converter: FVD states no CARB certification or TÜV approval. Check Bischoff flange and OBD1 one-sensor application. No horsepower or weight-saving claim is independently verified.

The genuine option is a used marketplace component and should be inspected before installation. Its seller title calls the unit Bischoff, which conflicts with Porsche Classic PET's GILLET attribution; confirm the stamping and exact flange before purchase. The DANSK product is a catalyst-delete performance part, not an emissions-compliant catalytic converter; check local road, emissions and homologation rules before use.

The alternative is listed for 993 Turbo and GT2 applications. Confirm engine and emissions specification, air-pump routing, ports, heat exposure and clamps before ordering.

Porsche PET lists this cylinder at illustration 702-09, position 12. It is the Turbo-specific G64/51 application and must not be substituted with the naturally aspirated 950 116 237 12 or 964 Turbo 950 116 237 50 cylinders. Confirm Turbo model, transmission and VIN before ordering. FTE is recorded as an alternative manufacturer, not as a proven Porsche production supplier.

The current Genuine Porsche order reference is 993 116 911 01.

FVD123010 is a race-use performance alternative, not evidence that FVD supplied the Porsche production actuator. FVD says two are required per car and recommends the product only after matching higher-boost software; it also disclaims emissions compliance. Confirm the turbo, software, boost target and paired-actuator setup before ordering.

This is the 76-tooth, 25 mm-wide power-steering belt for the 993. Do not substitute the differently dimensioned 964 belt merely because some catalogues group the applications.

Genuine-link dates and original-equipment-maker evidence have not been refreshed in this batch. The described gasket is between the oil tank and level sender. No rubber, cork or fibre composition is specified.

Confirm thermostat-housing revision and replace the specified seal according to the workshop procedure. The aftermarket listing is not evidence that Hamburg-Technic supplied Porsche original production.

Confirm the front wheel-arch oil-cooler layout, bracket orientation and surrounding damage before ordering. The aftermarket listing is not evidence that Hamburg-Technic supplied Porsche original production.

The canonical TEILE.COM URL allowed the Kitesurf user agent in robots.txt but returned a Cloudflare HTTP 403 challenge to both Kitesurf and local Chromium; the public Elfer.pl mirror rendered the same TEILE catalogue product and is therefore used as the purchase link. No source checked here proves the Porsche production supplier. This is a tandem steering/clutch pump and the FVD alternative is an exchange item with a core deposit: confirm Turbo/GT2 model, LHD/RHD, connections, core eligibility and shipment terms before ordering.
