CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your F2X/F3X 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.

Routine Maintenance
Size: (Pack of 1)
This is my go-to replacement when I conduct maintenance on my personal vehicle. The item is amazingly easy to install (use YouTube tutorials if necessary). The quality and value for the money is better than what I can receive at my local service center. The option to order this every six months as Subscribe & Save is worth it!

Great Engine Air Filter For Honda Accord Speed 2.0 2018
Size: (Pack of 1)
It is one of the 2 engine air filters available on Amazon for Honda Accord Speed 2.0 2018. I see the same quality as the original OEM engine air filter. Perfect fit. The other one is ‎K&N 33-5074, but at a much higher price.
