Overview:

Keep the check engine light off with MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 55321. 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 1997-2002 Ford E-250 Econoline, 2000-2004 Ford E-350 Super Duty, 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 starter was sold at a great price. I was kinda Leary on buying it at the price advertised at but went with it. It bolted right up and have had no problems with it.

If you have a 2001 Dodge Ram 2500 24v 5.9 Cummins, buy it.! But read my review to the end.
Style: 17548N
So far, so great.! Put this in my 2001 Dodge Ram 2500 24v 5.9 Cummins. Bolted right up and fit perfectly. The small ground wire placement was different, a post and screw, instead of a post bolt and nut. But no problem there. I'll tell you what, I've never heard my engine turn over so quickly. This bad boy is torquey and fast.! Says it has a year warranty, and I will immediately update if there are any changes whatsoever.! The main reason I wanted to make this review, is because of how few reviews this has. And trust me, buy this starter, and rebuild your old ORM one for backup. The Delo starters are cheap to rebuild, and last forever.! I highly recommend buying, and i hope your luck is as good as mine.!?

Perfect fit for my 2018 Civic—easy, affordable, and worth it
Size: 9.5" x 10.9" x 2.1"
I’ve bought this cabin air filter multiple times for my 2018 Honda Civic, and it’s consistently great quality. It fits perfectly and is super easy to install—takes just a few minutes to swap out, and I always do it myself. Way cheaper than going to a shop or dealership. The airflow is smooth, there’s no smell at all, and it keeps the inside of my car feeling clean and fresh. No weird odors, no dust blowing in—just a solid, dependable filter that does its job well. This is the only one I’ll keep buying.
