Wix 46844 air filter for the 1994-2000 Peterbilt 357 6-cylinder 10.8L and other vehicles traps dust and dirt before it reaches the engine. Wix HD air filters are recommended for OEM air filter change intervals.
Weak power, lower fuel economy or dirt packed into the pleats can mean the filter is worn out; a clogged fuel filter or a leak in the intake piping may be behind the power and economy complaints instead, so find the cause before you replace it. The engine takes one filter.
It fits the 1994-2000 Peterbilt 357 6-cylinder 10.8L and the 1989-1996 Peterbilt 378 6-cylinder 10.3L.
