Fitment Notes

• CSF 7241 is the left (driver's side) radiator - the complete upgrade system for the 992 consists of CSF 7241 (left), CSF 7242 (right), and CSF 7243 (center); the left and right can be purchased and installed independently
• Replaces Porsche OEM part number 992.121.251 (left side)
• True drop-in fit - mounts directly to factory ducting, AC condensers, and mounting brackets; no cutting or modifications required
• Most 992 Carrera models (Base through GTS) were not factory-equipped with a center radiator - only the Turbo, Turbo S, GT3, and 992.2 GTS hybrid received one as standard; center radiator availability also varied by package and region on some 3.0L Turbo models
• The 992 GT3 RS uses a single large center radiator (Porsche: 9GT-121-253-A) rather than the standard three-radiator layout - CSF 7243 center radiator does not fit the GT3 RS; CSF 7241 (left) and 7242 (right) do fit
• For 992 models not originally equipped with a center radiator, adding the CSF 7243 is possible using OEM Porsche hardware - see the CSF 7243 listing for details

Features

• 2-Row 42mm all-aluminum core - a significant upgrade over the factory single-row plastic-tank design, increasing coolant fluid capacity and total heat dissipation surface area substantially
• CSF's exclusive B-Tube technology - seam-brazed B-shaped tube cross-section increases heat transfer surface area by approximately 15% over conventional oval welded tubes, delivering dual liquid laminar flow within the same core footprint
• New 5mm multi-louvered "track-spec" fins (introduced late 2023) - the tighter fin pitch significantly increases heat exchange surface area and, combined with B-Tube technology, achieves up to 25% improvement in total heat transfer efficiency over standard tube designs
• 100% TIG-welded all-aluminum construction - eliminates the plastic tank cracking and seam leakage failure modes of the OEM single-row radiator, and provides the structural strength needed for sustained high-load track and performance driving
• CNC machined mounting brackets and OEM-style inlet/outlet connections - plug-and-play installation using factory hardware; no modifications to ducting, AC condensers, or mounting points required
• Hand-brushed satin finish for a premium, purposeful appearance in the 992 engine bay
• Individually pressure tested before shipment

Product Description

The CSF 7241 is a high-performance all-aluminum left-side radiator for the 2019-present Porsche 992 generation 911, covering the full model range from Carrera through GT3, GT3 RS, Turbo, and Turbo S on both 992.1 and 992.2 platforms. The factory 992 cooling system uses plastic-tank single-row aluminum radiators - a construction that is adequate for road use but falls significantly short under track driving and high-performance builds. Porsche compounded this limitation by omitting the center radiator on most Carrera and Targa models, leaving owners with reduced total thermal capacity. Many 992 owners report elevated engine temperatures after a few track laps and some experience thermal protection interventions at sustained high loads.

The CSF 7241 directly replaces the OEM left radiator with a 2-row 42mm all-aluminum TIG-welded core featuring CSF's proprietary B-Tube technology and the latest 5mm track-spec multi-louvered fins - together delivering up to 25% improvement in heat transfer efficiency over the factory unit. Installation is plug-and-play using all factory ducting, AC condensers, and mounting brackets with no modifications required, replacing Porsche OEM part number 992.121.251. The 7241 pairs with CSF 7242 (right side) for a complete side-radiator upgrade, and optionally with CSF 7243 (center) to add or upgrade the center cooling circuit - with the exception of the GT3 RS, which uses a different single large center radiator and does not accept the 7243.
