ATP Intake Blast Intake System Cleaner

ATP Intake Blast intake system cleaner works to remove carbon and oil deposits that accumulate over time, helping eliminate rough idle, hard starting, loss of power, and pinging. This easy-to-use, aerosol-charged solution applies a highly concentrated cleaning solvent through the plenum, ports, and valves of your intake system, effectively removing deposits. The system cleaner also eliminates the need for additional hoses—and offers an aerosol solution to a solvent that historically had to be suctioned into the vacuum hoses from a separate container. ATP Intake Blast formula is smoke-free, as well as catalytic converter and oxygen sensor safe.
