This grommet has the proper pliability to install in an extremely tight area.
Rubber is pliable and goes in perfectly.
I have a 1978 Chevy Monza with the Buick 231 V6 I am restoring. The 40 year old grommet did not come out of the intake manifold in one piece and I needed a replacement. Over the counter/Dorman products do not fit this application although listed that they do. Highway Stars product fit the manifold and PCV perfectly.
After buying 5 different PCV grommets that did NOT fit in the hole from different AUTO PART STORES, I purchased this one=A PERFECT FIT!!
