DHM Billet Valve Cover Set with Oil Ports for the 2022+ Honda Grom / Monkey


You now have the option to plumb your own oil cooler setup using our billet valve covers!

Machined locally from 6061 aircraft grade aluminum, our valve cover set helps to dissipate heat while also offering an option to route your own oil cooler using the two M10 banjo ports. If you don't need to run an oil cooler, a bypass is included. These covers will re-use your stock o-ring gaskets. New stainless hardware is included to bolt them on to your cylinder head.

Haven't installed these yet but look great and very well made.

Look great!

Running an oil cooler on a 22+ Grom or Monkey, these are the finest valve covers on the market. Fit, finish, and of course function, all what is to be expected from DHM. Highly recommend.

Great product!

Quality product that allowed me to plumb my oil
cooler in.

Timothy Clamp
Great product and service

The covers are very well made and designed. I had a question about whether a high flow oil pump was required to push the oil through an external cooler, and David replied right away to tell me the 22+ Grom has been designed to flow oil through a port on the case. Great service, thank you!
