Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51943. 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. Designed to fit the 2007-2008 Audi Q7 and 2007 Volkswagen Touareg, this direct-fit catalytic converter also interchanges with OE parts 7L6 254 301 MX, 7L8 254 300 KX, among others.

They need to find a better way to ship it
Style: 1 gal
What was left in the bottle worked great. However, the cap was off of the jug when I opened the package. Ididn't have enough for the other tires.

Great Spark plugs!
Work Great In My 18.5hp Kohler Engine. The engine is on a Craftsman riding mower, and it drives and runs great.

Spark-tacular Revival for My Lawn Chariot
Ordered this OEM 2-pack of Champion spark plugs (Kohler 25 132 23-S / 2513223S) for my Kohler Command K OHV 7000 series (KT725) engine, and let me tell you—these little lightning bolts mean business. Installation? Easier than pretending I’ll read the whole owner’s manual. Pulled the old plugs, threaded these pre-gapped beauties in, torqued appropriately, reconnected, and boom—instant ignition enthusiasm. The engine fired up like it had just downed a double espresso. It’s still too early in the season to mow, but I couldn’t resist a test run. Converted the tractor mower into a full-blown leaf-blasting machine and sent it down my 1/10-mile driveway like a suburban hurricane. Leaves scattered. Neighbors stared. Power was smooth, responsive, and downright smug. Idle is steady. Throttle response is crisp. No sputter, no hesitation—just clean, confident combustion. Exactly what you want from OEM-spec plugs. If your tractor’s been sounding like it’s negotiating with itself before starting, do it a favor. These plugs brought mine back to “runs like a champ”… which, given the name, feels poetically correct. Five stars. Lawn domination pending.
