Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551419. 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 Chevrolet Silverado 1500, 2003-2005 Chevrolet Tahoe, and additional vehicles. 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 be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Oil pressure drop
Once the engine warms up, the oil pressure drops enough to trigger the check engine light every time it dips below the threshold. I decided to try an aftermarket oil filter, but it looks like I’ll be switching back to the pricey OEM one after all.

Perfect OEM replacement
An amazing alternative to the expensive OEM filter. Works just as well if not better.

Parts that fit!
It’s hard to find ‘official Mopar’ parts for the 3.0 Eco Diesel but Doc’s Diesel are exact matches and are as good or better quality as factory.

Just like the OEM filter
Color: 3 Set
I bought these awhile back before needing one. Did my oil change a couple months ago, wanted to wait a bit to review it. Fit is identical to the OEM filter, nice it also comes with new retention cap o-rings. Can recommend, seems to function as well as name brand/OEM and a good value since purchasing more than one. Literally got one for free compared to single purchase of 3. I drive my company 2012 Caravan about 35-40k a year, so I change my oil about every 3-4 months. I also have the upgraded all aluminum oil cooler, so I have to use this filter for the later models.
