You are looking at a replacement paper air filter element for the 2 stage GPM Air Filter Kit.

This sale is for a brand new replacement air filter cartridge refill in the GPM 2 stage air filter kit. (Does not include entire new Aluminum Air Filter kit> Email us for those) (The entire kit fits most .21 engines with a 13-15 mm intake, and generates a massive 5.3 square inches of available airflow. )

This kit is an exact replacement for the paper element cartridge in the air filter kit. Everything pictures is included. BRAND NEW!

GPM has produced this paper air filter to allow the absolute maximum air flow to reach your high tech .21/.26 RC Nitro engine. The external foam filter blocks out all course debris, while allowing the bulk of air to reach the innermost filter, where the remaining finer dirt granules are captured.

Real World Tips: Replace as necessary. Don't replace if the element is just a little dirty. Use your best judgment to determine if its clogged. If it is in the slightest, replace.
