CSF BMW B58/B48 Front Mount Triple-Pass Heat Exchanger w/Rock GuardThe original OEM B58 heat exchanger is a 1 row unit that is 27mm thick. In comparison, CSF has used its industry exclusive world's largest 2 row core (68mm) with CSF's B Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high performance heat exchanger is its unique triple pass flow design. The water traveling through the upgraded heat exchanger

The original OEM B58 heat exchanger is a 1-row unit that is 27mm thick. In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures.

Highly Recommended – Saved Big and Easy Install at 83 Years Old!
Size: CF10134&CA11476
I’ve been taking my cars to my favorite garage for over 25 years, so I trust them completely. When they quoted me $150 just to install and purchase the cabin and engine air filters on my 2016 Honda Accord, I decided to try doing it myself. I bought this Cabin & Engine Air Filter set (fits Honda Accord 2.4L 2013-2017 and Acura TLX) for only about $27 delivered. What a difference in price! Installation was surprisingly straightforward. Everything fit perfectly with no issues. The only extra step was doing a simple factory reset on the control panel, which was very easy and took just a couple of minutes. At 83 years old, I’m proud to say I handled the whole job myself in my driveway. The filters seem high quality, especially with the activated carbon cabin filter. My car runs cleaner now and the air inside smells fresher. Excellent value and perfect fit. If you’re even a little handy, don’t pay the high dealer/garage prices — get this kit and do it yourself. Highly recommended! Would buy again without hesitation.

Perfect Fit & Performance for 2022 Explorer ✅
Size: CA10242&CF12772, Size: CA10242&CF12772
I recently installed this filter set on my 2022 Ford Explorer (2.3L), and I’m very impressed with the results. Both the engine and cabin filters were a perfect fit with no installation issues. Performance & Quality: Solid Build: These feel much sturdier and higher quality than the filters I removed. I bought my vehicle used, and it seems the previous owners used whatever generic parts they could find. These are a noticeable step up. Fuel Efficiency: Since the swap, my MPG has remained rock steady at 26.1 MPG while running 89 octane fuel. It’s good to know the engine is breathing efficiently. Cabin Comfort: The cabin air is noticeably fresh, and the airflow is excellent—no whistling or restricted feel through the vents. Value: Getting both filters in one set is a great deal compared to buying them individually at a local auto parts store or the dealership. I’ll definitely be looking at these again in the next 6 to 12 months for my next maintenance cycle. Bottom Line: If you’re looking for a reliable, cost-effective alternative to dealership prices that doesn't compromise on performance, this is a great choice. See Old vs New Photo
