Why Walnut Sand is the Only Way to Rescue Your Gasoline Direct Injection Engine?

How to choose the intake air control valve cleaning for car repair shop?
Is Your direct fuel injection Engine "Choking" on Carbon?
The culprit isn't a broken part—it's Carbon Buildup. Because fuel never washes the intake valves in GDI engines, sticky carbon deposits bake onto the valves, literally suffocating your engine.
You might be researching solutions and seeing options like Chemical Cleaners, Dry Ice Blasting, and Walnut Blasting. Which one is right for you?
Why Walnut Blasting Wins for independent car repair shop & DIYer
Let’s look at the alternatives mentioned by many workshops:
Chemical Additives (The "Snake Oil"): Pouring cleaner in the tank does nothing for intake valves on a GDI engine. It’s a waste of $20.
Dry Ice Blasting (The "Overkill"): While effective and mess-free (as dry ice evaporates), the machines are incredibly expensive (often $3,000+) and require specialized dry ice pellets that are hard to store.
Walnut Blasting (The "Gold Standard"):
Safe: Walnut shells are organic and softer than aluminum, meaning zero damage to your engine metal.
Efficient: It physically blasts away 100% of the carbon in minutes.
Affordable: With the TPMSAuto HTS686, you get professional results for a fraction of the cost.
Why Choose Walnut Blaster Over Other "Generic" Blasters?
Many competitors on the market only provide 5 basic adapters.
But in the real world, a BMW intake port is shaped differently than an Audi or a VW. Using a "one-size-fits-all" adapter leads to messy leaks and walnut dust flying all over your garage.
The TPMSAuto Walnut Blasting Machine Advantage:
✅ 14-Piece Professional Adapter Kit: We include nearly 3x the adapters of our competitors. Whether you have a square port, round port, or oval port, we guarantee a sealed, clean fit.
✅ Closed-Loop System: Like the pros, our machine blasts and vacuums simultaneously. No dust, no mess.
✅ High-Efficiency Motor: Powerful suction separates the carbon from the sand, allowing you to recycle the media.

Match: Select the perfect fit from our 14-piece adapter set and insert the blast nozzle.
Blast: Pull the trigger! The machine scrubs the valves while vacuuming the debris. In 1-3 minutes, your valves will look factory-new silver.
