Featuring the revolutionary 10 ft. MaxReach Straw, GUNK makes cleaning GDI intake valves effortless. Sit behind the wheel, rev the engine, and spray! No helpers needed - just you, your engine, and pro results! Specially formulated to dissolve 77% of carbon deposits in under 1 hour.
I bought the GUNK intake valve cleaner and it worked fine, but the can started leaking after a few uses. It was messy and annoying to deal with. I contacted customer service, but I expected better quality control for the price.

Not impressed with results
I was really hoping the GUNK 11oz GDI Intake Valve Cleaner would make a big impact, but I didn’t notice much difference in my engine. Maybe it works better for others, but for me, it was just okay.

Decent product, some issues
The GUNK intake valve cleaner did help reduce carbon buildup, but the spray nozzle was a bit tricky to use at first. Also, I wish it came with better instructions. Still, it worked better than my previous cleaner. Not bad overall!

Great for engine maintenance!
I've been using the GUNK 11oz GDI Intake Valve Cleaner for a few weeks now, and it’s made a noticeable difference in my car's performance. The engine runs smoother and the throttle response is much better. Highly effective for keeping things clean!

Really helped my gas mileage!
Used the GUNK cleaner last weekend, and I’m shocked at how much smoother my ride is now. Even my gas mileage seems improved! It’s simple to use and I’ll definitely keep this one in my garage. Worth it!
