As an engine wears, the clearance between the valve stem and guide increases; as this gets beyond tolerances the car will tend to smoke under deceleration (when you take your foot off the throttle). Good valve stem seals will allow for greater wear before the smoke becomes intolerable. These were an improved material with little springs in the neck to help create a better seal than the original AEG327 seal. 8 Required per car- must have grooves on the valve guides to fit. Fits the 12G1963/C-AJJ4037 valve guides with the grove.Upgraded version (Viton) is available as LJQ101160 Show more
