BOV Kompact EM Plumb Back VR21 - Tank 300
The BOV Kompact EM Plumb Back VR21 - Tank 300 is a genuine Turbosmart performance part designed for reliable operation, precise fitment and proven results on street and track builds. This product is supplied with the technical notes: Bolt-On Upgrade for Factory Diverter Valve.
The multiple award-winning Kompact EM Series of upgraded Blow Off Valves is the world's first truly plug-and-play upgrade solution for your factory diverter valve. Unplug and unbolt your OEM valve, and install a Kompact EM valve in its place. No adaptors, hoses, or extra assembly are required.The Kompact EM Valve Series from Turbosmart takes motorsport-proven billet valve technology and adds an onboard, proprietary solenoid system and internal pressure control channels, resulting in a simple plug-and-play valve with full OE integration and control. There are no reference hoses, no separate solenoids, and no fiddly bits - Just bolt-on and plug in!
You can count on unmatched performance and reliability as a direct replacement for your factory diverter valve. The Kompact EM Valves overcome the common faults associated with plastic factory valves through our Boost-Balance Valve Design (the more boost you have, the better it seals), a positive seal O-ring on the piston's face, and billet construction. No matter your application, the Kompact EM Series will hold more boost and be more responsive in any environment.

Fixes flats and old tires like a charm
Style: 1 gal
This stuff is awesome. If you have tractor tires, ATV tires, bike, tires, hell, any tires that hold air. This stuff is awesome. Awesome. Awesome. It does not work for highway vehicles, i.e. Cars and truck trucks. But anything else it’s great. Dollies, air compressors, wheelbarrows, the stuff is awesome dude.

slime is and has always been amazing for bike tires and other small pneumatic tires
Style: 1 gal
this is a great value, I have been using slime in my tubes of my bikes and a small inflatable pneumatic tires for probably 30 years, and I can say slime has only improved, and it works fantastic, this is a very good way to save money, and it works great on goat heads and several other ways your tires can get punctured, I still always recommend carrying a small air compressor or pump, but for the price point you just cannot beat slime, every bike shop should always carry this.

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.
