Installation is a snap. Simply tighten the set screw that is preinstalled on the cap. We provide the allen key too. We also recommend a bit of clear automotive silicone be dabbed on the underneath of the cap. Allow to setup overnight if choosing to apply clear silicone. Install this cap when your engine is cool.
392 Owners please read:
It has been brought to our attention by numerous concerned customers as well as some local dealer networks that there is currently a TSB out instructing 392 owners to use 0W-40 synthetic oil NOT the 5W-40 as originally was put in the factory manuals and factory oil caps. All customers placing orders for 6.4L (392) engines will receive
0-W40. If you have any questions please call.
