Thank you. You have rated this product.
High-demand cars such as turbocharged, supercharged, and racing applications need maximum cooling ability. For many years the next-step beyond the standard aluminum radiator upgrade was to move on to a custom multi-pass racing radiator. Those radiators packed massive cooling ability, but also come with massive price tags and are not direct-fit; required custom brackets, didn't fit with factory fans, and so on.
Our new Triple-Pass radiator is the first of its kind; a cross-flow, triple-pass configuration using racing radiator technology throughout that still drops in without any other modifications, and doesn't have the price tag that comes with "custom". Fits with the factory brackets, fans, and hoses.
- Triple-pass flow design makes the water pass fully from one side to the other through the radiator THREE times instead of ONCE, more efficiently using ALL the frontal area of the radiator and giving the water more time to shed heat.
- Advanced fin and tube technology:
Utilizes CSF's specially-engineered "B-tubes" which are made from thinner and lighter aluminum but are still stronger than conventional 0-shape tubes. The core features louvered fins with a denser packing. More fins per inch than standard cores means more surface area for cooling and thus dramatically higher efficiency.
- 32mm core for peak efficiency and light weight:
Conventional high-performance radiators with low fin counts and standard tubes have no choice but to increase the core thickness to get more cooling. This core is about double thick compared to stock yet still less than two inch race cores. The two inch core units slows down the air more, and that hurts efficiency, so you get diminishing returns as the core gets thicker and thicker. A thicker core also means a heavier radiator. The new generation of radiator advances used in this unit allow us to achieve a new "best" for cooling ability without any need to dramatically increase core size. This 32mm core allows for fast airflow, further improving performance, and keeps the weight well below classic 2 inch thick racing radiators. The thin core also means the unit can drop in in place of the factory unit without the need for relocating anything.
BRIAN'S APPLICATION NOTES: This project started after I lost a 2.5 liter motor in my 2006 to overheating. The motor didn't actually fail but got hot enough for piston ring tension to be seriously compromised with resulting loss of peak horsepower of nearly 20 percent...OUCH. We ended up rebuilding that motor with high compression pistons and I had learned my lesson on giving an upgraded NC as much cooling as available. At about the same time we decided to push our supercharged 2.0 2007 to over 300 hp and found we needed more cooling in that NC than our current selection of radiators could provide. Thus, for those racing boosted 2.0 and 2.5 and those racing even normally aspirated 2.5 we suggest this is a critical insurance policy that saves you money in the long run! Works great in combo with our singular hood vents (which draw even more air through the radiator).
The factory radiator hoses will install as-is on this radiator. However, we like to trim 1.25" of length off the driver's side hose on the end that connects to the radiator for perfect fitment.
