The Allstar Performance ALL40325 down nozzle breather rings are used on mechanical fuel injection nozzles. Each ring lets air pre-mix with fuel inside the nozzle, which eliminates engine vacuum drawing fuel into the engine. Once the engine is shut down, the filter lets excess fuel evacuate the injection lines to help prevent fuel from entering the cylinders. The low profile filter design reduces the chance of damage. Sold as a pack of 8.
