CRC Throttle Body & Air Intake Cleaner (12 Oz)

Carbon and varnish buildup on your throttle body can cause rough idle, hesitation, and poor fuel economy, and it tends to sneak up on you over tens of thousands of miles. CRC Throttle Body and Air-Intake Cleaner in this 12 oz spray can is formulated to dissolve that buildup and restore smooth throttle response.

Safe for use on all gasoline fuel injection systems, including throttle body, multi-port, and GDI setups, this cleaner works on cars, trucks, SUVs, motorcycles, boats, and small engines. The spray-on formula cuts through gum, varnish, and carbon deposits on throttle valves and bores without leaving residue behind. A clean throttle body means easier cold starts, smoother acceleration, and more consistent idle.

Application is straightforward. Remove the air intake hose to expose the throttle body, spray the cleaner directly onto the butterfly valve and bore, and wipe away loosened deposits with a clean rag. Most vehicles take about ten minutes from start to finish.
