Whether it’s for a runabout, bass boat, or center console fishing boat, Sierra is dedicated to producing the best performing, most reliable filters in the world.
Today’s high tech engines require precise amounts of fuel, oil and air to operate at peak performance. Older carbureted engines did not use air filters because the environment they ran in was considered “clean” enough that none were required. However today’s fuel injected and computer controlled engines monitor every aspect of engine operation. That “clean” air is no longer clean enough.
Air filters have become more prevalent on today’s outboard engines, and Sierra offers OEM quality replacement filters that meet or exceed the OEM for those needs. Sierra outboard and diesel air filters are designed and tested for the marine environment, and just like everything we do, they are backed by the best warranty in the marine business. Sierra’s Limited Lifetime Warranty!
Sierra is the industry leader in 10-micron technology. Sierra filters not only protect your engine, they are over 90% efficient at removing engine damaging 10-micron and larger particles without starving the engine for fuel. Don’t be fooled by other 10-micron imitators that don’t list their efficiency. Sierra filters are independently lab tested and approved.
