Sierra Oil Filter 18-7879-1 for V6 4.3L Marine Engines, Replaces 35-883702

The Sierra 18-7879-1 is a spin-on oil filter engineered for V6 4.3L marine engines. It is designed to trap contaminants from engine oil while maintaining proper oil flow, helping protect internal engine components during operation. The filter housing is constructed of plastic and threads onto the engine block using an M16 x 1.5 thread size.

This filter is specified for a range of V6 4.3L (262 cid / 263 cid / 264 cid / 265 cid / 266 cid / 267 cid) engine variants, including 175 hp, 185 hp, 205 hp, 262 Mag EFI, and the 4.3L / LX / LH / LXH, 4.3L, 4.3L EFI, and 4.3L MPI engine families. These engines take 4.3 liters (4.5 quarts) of 25W-40 FC-W rated oil when serviced with this filter. Note that V6 engines equipped with the oil filter relocation option require a different filter, the 18-7824-2, rather than the 18-7879-1.

The Sierra 18-7879-1 cross-references directly to OEM number 35-883702, making it straightforward to identify as the correct replacement filter when servicing eligible V6 4.3L marine engines.
