Air filter
Teleflex Marine

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!
