OEM 1970/72-74 Mopar 340/360/383/400/440 Air Cleaner Valve Cover Breather. This is an original air cleaner breather filter that has been cleaned and refinished. It is correct for 1970 & 72-74 models that use the single breather filter that pushes into the RH/Passenger side valve cover grommet. 

This piece is in good condition and will replace an incorrect or missing breather filter.  


For further information on the restoration process, please contact us. 



This assembly is correct for the following 1970-74 340/360/383/400/440 high performance models:

GTX, Road Runner, Superbird, Sport Fury, 'Cuda, Sport Sebring, Barracuda Gran Coupe, Duster 340/360

Note: this part will fit the 71 models, but is incorrect due to the year only 3 way valve incorporated. Some 73-74 models featured the shorter tapered breather filter as well.
