If your engine's feeling sluggish or you're noticing rough idling, it might be time for an intake system clean. This 3M Professional Intake System Cleaner is a 9 oz aerosol designed to break down carbon deposits in the throttle body, intake valves, and manifold. Just use it with the 3M adapter (sold separately, part 08960) to spray directly into the intake. You'll likely notice smoother acceleration, better fuel economy, and fewer engine knocks or pings. It's a pro-grade formula, so it's strong stuff — meant for industrial or occupational use, but great for DIYers who know their way around an engine. An affordable way to keep your ride running clean and responsive without a pricey shop visit. Just remember: always follow the instructions and use in a well-ventilated area.
