The KoKoMo Smoker Box Insert accessory is the perfect upgrade and will fit perfectly inside the 3, 4 and 5 Burner Kokomo Pro and Classic Series Grills. Add your favorite wine, juice or marinade to the smoker box for extra flavoring - sits directly beneath the cooking grid saving valuable grilling space. Use flavored wood chips or wood pellets for a great smoky flavor and easily add or remove it depending on what you are cooking.
