Re: Aftermarket intake reeds
The fiberglass or carbon fiber reeds usually improve idle over stock. Certainly will help if yer stock steel reeds are out of spec.
Another key feature is that if they do fail, the fiber reeds are less likely to cause serious engine damage. The steel reeds almost always hurt somethin' else if they break.
Some folks make their own from printed circuit board material, or carbon fiber base stock. Printed circuit material is FR4, .023". Carbon fiber is either .013" or .020" carbon fiber stock from robotcombat.com or other places.
The latest rage is ss reeds and rubber coated blocks.
