Losi LOSB5027 Pull-Start Pre-Filter / 23-30CC Gas Engine / 5IVE-T

The Losi LOSB5027 is a pull-start pre-filter built for 23-30cc gas engines and the 5IVE-T. This pre-filter sits ahead of your engine's main air filter, catching larger dirt and debris before it reaches the primary filter element, which helps extend the life of your main filter and keeps your engine breathing cleaner air overall.

Running large-scale gas engines in dusty or dirty conditions puts real strain on your filtration system, and a clogged or missing pre-filter can lead to reduced engine performance or, over time, premature wear from contaminants making it past the filtration stage. Because this pre-filter is a wear item that collects debris by design, periodic replacement is part of normal maintenance for anyone running their 5IVE-T regularly in outdoor conditions. This genuine Losi part matches the factory fitment for 23-30cc gas engines, installing directly onto your existing air filter assembly. Keep a spare on hand to maintain clean airflow and protect your engine.
