ATTENTION!! This adapter is available for testing! The adapter has been tested for proper fitment and has been tested for durability against the walnuts. However this adapter has not been tested for use in the real world on an engine. I am offering this adapter to anyone that would like to test it. This adapters allows you to use the walnut blaster supplied with the Honda fit carbon deposit bulletin. Adapters are FREE with any purchase of $5 or more, for anyone who would like to test them. Use code WALNUT for free ground shipping on your entire order when the adapter is added to your cart.
Note: These adapters may come in black or white.

Through your feedback we have been able to make some changes to this adapter. These include a smoother transition from flange to vacuum tube. And larger support around the bolt hole area. This allows use of the Oem intake manifold bolts without the need for washers or spacers. Reach out to us to share your thoughts on the 1.5T Walnut Blasting Adapter
