Read articles →This isn't a general review but a narrow deep-dive on cross-referencing oil filters for the Bad Boy 4035H, from an owner with about 350 hours on the machine. It covers the OEM Kuok J part number, Napa Gold and Wix equivalents, bypass PSI differences (Baldwin's 20 PSI vs the stock 8-11), and a specific larger-volume filter swap (SL7237) with real-world cold-start results. Best for current owners doing their own maintenance.
