"B-Tube" technology - Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in a 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 (better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded.

The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tube by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow."

The tubes are made from aircraft grade special clad aluminum and are intricately formed on our high precision 6-stage tubeforming mill. No other aftermarket radiator manufacturer uses this technology. This technology raises the bar and sets the standard for high performance radiator cores.

Brian's Application Notes: Though we continue to be big KOYO fans here, we recently tried an NC application CSF here for a customer 2.5 motor conversion and were so impressed with both fit and finish, including first rate quality on the welds and complete brackets, that we decided we must offer these to all our customers.

Radiator cap INCLUDED

Automatic Transmission: This radiator fits both manual and automatic cars, but it does NOT have a transmission cooler built into it for the auto transmission (factory automatic radiators have a transmission cooler integrated in to the radiator). This means you will need to install your own separate transmission cooler to attach the lines that come from the transmission to.

BRIAN'S INSTALL NOTES: Sometimes we find the A/C was port installed and placement of the condenser is not always consistent, we just bend the condenser brackets as the easiest way to get the clearance. But you can also unbolt the Condenser and slide it down and then put it in front of the brackets. Be sure you make clearance so your new radiator is not damaged by the condenser!

CSF #2863 Miata 42mm Two Row Radiator

Purchased this to replace an OEM leaking radiator (at the top plastic). Radiator was beautiful coming out of the box. Very impressed! Like others have mentioned, I had to push the AC condenser out of the way a little bit to fit it towards the front of the car. Was a little disappointed it didn't come with new hardware and had to go to local store and buy different size bolts as the factory ones were too long. I also had to take a Dremel and cut some of the shroud off one side of the OEM fan shroud to prevent it from causing interference with the radiator. Knowing most of the issues before purchasing I knew what to expect and you can't always assume a twice as thick core will fit perfectly. Temperatures seem to be fine and no more leaks. Love that the drain plug is a metal hex head instead of a plastic phillips bit like the OEM one has.

Great build quality. My dad wasn't very happy with me spending $200+ on a radiator until he saw it in person. It is a very nice piece. Dropped right into place like it was OEM even though it's twice as thick. The only thing I had to "modify" was the OEM fans need a thick washer for them to seat right (as other reviewers have mentioned). I also saw other reviewers mentioning bending the ac condenser bracket but I personally did not have to do this. I've had it in the car for about a month now and could not be happier. Temps are great.

A work of ARt! My son designs heat exchangers for refineries, and was quite impressed with the fit, finish and obvious cooling capacity. The OEM radiator looks like a joke compared to this monster!

Got this installed and it works wonders for cooling. I have a supercharged 2001 LS and on boost it was running in the 217 range and about 199 off boost. Installed this radiator and now running no more than 197 at anytime. Idles around 180. Seeing about 20 degree cooler temps. Installed using the SAMCO Silicone hoses. Make sure to bend the condenser brackets or you will be smashing the radiator in to it. Also will need to get new screws for the stock fans. I used 6 #6 1.00 10mm screws and 2 #6 1.00 16mm screws. Goodwin suggested to use the stock fans if they are working properly and seem to be doing the trick. Had plenty of room except the power steering reservoir bracket was custom made to fit the intake. Had to shave a bit off the bracket. Completely happy with my purchase and would recommend it to anyone.

The install of this radiator was simple and man is it shiny!. As to be expected I had to bend the a/c condenser mounts just slightly (about 4mm) to clear the radiator. Other fitment notes, the six factory screws that hold the fan to the back of the radiator are too long to be reused, I just went to lowes and got some that were 1/2 the length. Also the drivers side fan shroud had to be trimmed on the sides to prevent it from smashing the cooling fins. Besides that it went smooth. Install took under 2 hrs. No more high temps in stop-n-go traffic.

This radiator was a great value for the performance I was looking for. Construction is excellent, the welds were solid and fitment for the radiator was excellent. However, the mount for the NB fans was off on the lower drivers side peg mount which had to be altered for the factory fans to fit correctly. Also, the ac condenser had to be relocated due to the core size to avoid rubbing. Overall a 4 out of 5 mainly due to the inefficiency of down fall radiators. I recommend this if you can't afford a cross flow radiator.

This radiator was recommended by both Ryan and Sean. I am very happy with the quality of the unit. It was a perfect fit. Pulled one out and slipped the new one in. Easy. This combined with the Mishimoto fans and I'm set to beat the Fresno heat (102-112 in summer). So far, the car runs cooler than others I've seen or read about. If you want to think of the temp gauge as a clock face with cold at 10am and hot at 2pmm then the thermometer icon would of course be at the high noon position. My car now runs at about the 11:30 position and if I turn the air on and climb hills or drive it hard, it climbs up to the 11:45 position. It has yet to pass this position. Most articles I've seen has the temp gauge being more in the 12:30 to 1 position. I suspect this has to do with the high flow fans and the high air flow radiator. Couldn't be happier.

The unit fit well but required bending of the condenser brackets, no issue. The AC line bracket on the bottom of the fan mount needed re-engineering which took a little time, and my sway-bar mount brace interfered with the frame of the driver's side fan, but the Dremmel fixed that. In all it took about 2 hours with the AC bracket taking most of that.
The service from start to finish was fantastic. Good job Goodwin and Fed-X.

The radiator dropped right in, and looks very nice.. The fans bolted right up and the radiator used the rubber mounts off the stock radiator. Tomorrow we'll see how the car runs ... I installed this as a part of a timing belt job.
