California Manifold Catalytic Converter

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5631759. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed to fit the 2003-2005 BMW 325i and 2003 BMW 325Ci. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Noticeable Improvement in Engine Smoothness
Size: 150 ml, Pack of 1
I decided to try LIQUI MOLY Valve Clean to help keep the intake valves clean and maintain engine performance, and I’m really impressed with the results. After adding it to the fuel tank and running through a full tank of gas, the engine felt noticeably smoother and more responsive. It’s very easy to use—just pour it into the fuel tank as directed. I also like that it’s from LIQUI MOLY, a brand known for high-quality automotive additives. While it’s not a miracle fix for serious mechanical issues, it’s a great preventative maintenance product to help reduce deposits and keep the engine running efficiently. I plan to use it periodically as part of my regular maintenance routine.

Good for routine engine care
Size: 150 ml, Pack of 1
Definitely not a cure-all for major mechanical problems, but it works well as a preventative step. It helps lessen deposits and keeps the engine running smoothly. I intend to use it regularly as part of my maintenance schedule to keep everything in good shape.
