Designed, engineered and made through real-world experience.
APX CoolFlow was founded by Sultan Auto Workshop, drawing on years of hands-on experience and a deep understanding of the cooling challenges vehicles face, particularly in hot climates and demanding driving conditions.
More than a parts store
We are more than an online automotive parts store. We design, develop and manufacture specialized automotive solutions, including engine oil coolers, transmission oil coolers, advanced cooling systems, precision CNC-machined components, performance parts and other engineering solutions for a wide range of vehicles and applications.
Our product development begins by identifying real problems vehicle owners bring into the workshop. We then design a solution, manufacture its components with precision, verify fitment and test it at Sultan Auto Workshop. Based on the results, we refine the design for the highest possible efficiency, reliability and ease of installation.

From the workshop to your car
-
01
Find the problem
We start with a real failure owners bring into the workshop.
-
02
Engineer the fix
We design a solution for that specific problem.
-
03
Machine it
Components are manufactured precisely on CNC.
-
04
Test the fit
We verify fitment and test it on the car in our workshop.
-
05
Refine
Results feed back into the design until it’s right.
Custom design & manufacturing services
Our capabilities go beyond APX CoolFlow products. We also provide specialized custom design, engineering and manufacturing services for individuals, automotive workshops, companies and private-label brands.
We study each customer’s technical requirements and develop a suitable solution: from the first concept and engineering design to prototype development and precision CNC manufacturing, followed by fitment testing and refinement to suit each project.
