The Ultimate Foam Cannon + Snow Foam Combo

This kit combines two standouts in car care: the Rockcar Stealth Foam Cannon – Blackout Edition and Autostolz Snow Foam. Together, they deliver professional-grade foam, unmatched lubrication, and longer dwell times for a safer, more effective wash.

Rockcar Stealth Foam Cannon – Blackout Edition

Engineered for serious performance, the Rockcar Stealth sets a new standard for foam cannons:

• Unmatched Foam Output: A precision stainless steel mesh foamer and correctly sized orifice produce thicker, denser foam than any other cannon we’ve tested.
• Fully Serviceable & Customisable: Swap orifice sizes, replace parts, or upgrade hoses and filters — everything is designed to be maintained and modified.
• Durable Build: Solid brass body with a thick black epoxy coating for chemical and corrosion resistance, stainless steel fittings, and a reinforced wide-mouth bottle with accurate metric markings.
• Precision Controls: Fine-tune soap mix, foam spread, and spray angle for perfect coverage — even keep the bottle upright while spraying at different angles.
• Smart Bottle Design: Large, clear bottle with a long, filtered intake hose prevents clogging and ensures consistent foam, even when the liquid’s running low.

Autostolz Snow Foam – Maximum Lubrication & Dwell Time

This is the highest-foaming snow foam we’ve ever tested — and we’ve tested plenty.

• Ultra-Dense Foam: Creates a thick blanket that clings for up to 5 minutes, softening and loosening dirt before you touch the paint.
• pH Neutral & Safe: Won’t strip waxes, sealants, or ceramic coatings, and is safe on matte and satin finishes.
• Pure Pre-Wash Performance: No waxes or SiO₂ — just maximum foam and lubrication to reduce the risk of swirls.
• Real-World Tested: In Christchurch trials, it matched the cleaning power of strong alkaline pre-washes without the paint risk, leaving well-maintained cars so clean that a mitt wash wasn’t always needed.

Why This Combo Works

The Rockcar Stealth gets the absolute best from any snow foam — and Autostolz Snow Foam is formulated to take full advantage. The result is a safer wash, better cleaning, and that satisfying thick foam coverage every time.

Kit Includes:

• Rockcar Stealth Foam Cannon – Blackout Edition
• Autostolz Snow Foam (500ml) – High-lubrication, pH-neutral formula
• Your choice of adapter to fit your water blaster brand

How to Use:
Mix 30–90 ml of Autostolz Snow Foam per 1 litre of water in the cannon bottle. Apply to a dry vehicle, let dwell up to 5 minutes, then rinse from bottom to top. Always work on cool surfaces, out of direct sun.

Choose Your Adapter

To make sure your foam cannon fits perfectly, select your water blaster brand from the dropdown menu above before adding to cart.
We supply the correct adapter for your brand so you can connect instantly and start foaming.

Available Adapter Options:

• Ava
• Bosch
• Dewalt
• Karcher K Series (K2, K3, K4, K5, K6, K7)
  
• Makia
• Nilfisk
• Ozito - Ozito has two fittings, please check your machine.
• Ryobi - Royobi has two fittings, please check your machine.
• Stihl
• no adapter for machines fitted with 1/4" quick connects already, like larger petrol machines.

Note:  some of the new Ozito and Ryobi machines with their new short adapter are more difficult to twist the adapter in and out.  They don fit, but they are just harder to grab onto to twist in and out, please know this in advance, we don't know why they changed from what was a very good fitting, and this is the only fitting we could source that fits.  Ryobi make a fitting themselves, but it is long and plastic, and we worry it would break with the weight of over 1kg of full foam cannon, the apart we have is solid brass, and high quality, but it is tricker to get out.  

If you’re unsure which adapter you need, check your water blaster’s manual or contact us and we’ll make sure you get the right one.

We have spent a lot of time going to various hardware stores for years checking fittings and adapters, and making sure we have the right adapters to fit the models in New Zealand.  However water blaster manufacturers can change fittings form some models, and New Zealand is a great place for importing oddball models from around the world, so if your adapter doesn't fit, don't worry, you can swap it.  Send us a photo often adapter you got next to the fitting on the wand of the machine you have and we can arrange to swap it.
