Air Filter — Duramax 6.6L
★★★★★
Noticeable improvement
"Put this in my 2019 Silverado 2500HD. Better throttle response and seeing about 1.5 MPG gain on the highway. The old filter was way dirtier than I thought."

7.3L Powerstroke Coolant Kit
★★★★★
Must-have for 7.3L trucks
"Wish I'd bought this years ago. My 2002 F350 has 220k miles. Installed in 45 minutes and the first filter caught a ton of crud. Cheap insurance."

RV Water Heater Thermostat
★★★★★
Fixed our camper's hot water
"Our Atwood water heater kept tripping the ECO. Swapped this thermostat assembly in 15 minutes with basic tools. Water heats perfectly now. Saved $200 vs a mobile RV tech."
