    Product Description

    For 997 GT3 / GT3RS models, CSF Radiators produced a design approximately 15-25% more efficient, support attachment of all stock components such as fan shrouds and A/C condensers, and most importantly, to be much more durable than the stock units. This upgrade is ideal for tracked cars or for cars in hotter climates. The factory plastic end tanks can fail over time as the years and miles pile on.

    Along with the increase in cooling performance this CSF radiator also adds reliability to your cooling system by eliminating the plastic end caps through it's aluminum construction that are prone to cracking and leaking.

    Your radiator is an integral, and arguably, the most important part of the cooling system. It is designed to expel heat from the coolant via the small fins. Most radiators fail when the end tanks crack causing leaks, but higher mileage radiators which have missing or bent fins often are clogged up with debris which can also cause overheating issues as the radiator cannot expel heat effectively. If your radiator is in rough shape we recommend replacing it. We also highly recommend inspecting/replacing the upper and lower radiator hose at that time.

    Features
    Unique B-tubing technology provides more surface area and 10% to 15% more cooling efficiency than factory units.

    Durable aircraft aluminum materials and high quality craftsmanship ensures higher durability on track.

    Design supports all radiator components such as fan shrouds and A/C condenser. Perfect upgrade for your street car as well

    Features

    CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your 997 911 / 987 Boxster/Cayman running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.

    The CSF 997 911 / 987 Boxster/Cayman radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Trust the cooling experts at CSF for the best performing, highest-quality, and most reliable radiators.
