i have a 2003 screamin eagle deuce and im not sure if the air filter is a stage 1 high flow it is stock and has a black cover on the back where it mounts to the carb it is efi if it isn't does anyone know if i can use a screamin eagle stage 1 back plate ithe filter and my cover thanks to all that reply

 

I'm confused, a picture would help. This statement is confusing, "back where it mounts to the carb it is efi".

 

Ya +1 on pics

 

If it still has the black cover on the back of the cleaner, it is stock. The Stage 1 cleaner has the football with an open back.
