(1 review) Write a Review


NOTE: Walnut blasting is an advanced maintenance procedure and when done incorrectly can cause damage to your engine. We always recommend having your car worked on by trained and knowledgable technicians.

Subie Bros is excited to introduce the first ever Walnut Blasting Valve Cleaning Kit for the FA20DIT Engine. This kit will help you complete an intake valve cleaning service using a media blaster and fine grit walnut shell media.

This kit includes:

  • Subie Bros Intake Valve Cleaning Adapter Made With High Strength Nylon Plastic
  • Media Blasting Wand (with 1/4" NPT)
  • Rubber Stopper Plug
  • Adapter Lockdown Bolt
  • (Optional) 1/4" NPT Thread Adapter Installed on Wand (This is required if you are using the suggested Harbor Freight Blaster) 

    NOTE: Harbor Freight recently revised their blasting gun, we are working on a new adapter to fit the revision. Please see the images to determine if you have the revised or original gun. The REVISED gun has the interior nozzle surrounded by metal with a slight gap around it, The ORIGINAL design has the interior nozzle that protrudes out from the back with nothing surrounding it.

To use this kit you will need:

You can see an overview of the intake manifold removal process and also the procedure here: 

The Subie Bros Intake Valve Cleaning Adapter mounts on top of the cylinder head on the intake valve port which is secured by the adapter lockdown bolt. You can then attach your shop vac and use the side ports in insert the media blaster wand attached to your media blaster and perform the walnut blasting service. You must make sure the valves are closed when using the kit.

    Works as expected

    This kit worked exactly as I needed it to. Price is a little high for what you get, but since nobody else offers anything similar and the DIY crowd that would tackle a job such as this, I understand it.

    My only gripe with the tool is that the adapter that bolts to the intake port will lift up slightly during use, allowing some blast media to escape. Would have been nice to be able to use two bolts to hold the tool in place and maybe an o-ring.
