ATP AT-100 intake Blast offers the latest technology in top end engine cleaning. This easy to use, aerosol charged solution applies a highly concentrated cleaning solvent through the plenum, ports and valves of the intake system. Works to remove carbon and oil deposits that accumulate over time, helping eliminate rough idle, hard starting, loss of power and pinging. Recommended for traditional fuel injected engines over 75,000 miles (with repeated service every 25,000 miles.) critical for gasoline direct injected engines (GDI) as fuel does not flow through or clean intake plenum, ports or valves in these applications - recommended every 15,000 miles (specifically to defer more complex tear down style cleaning such as walnut Blast or parts washers.) this self-contained kit 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. The new chemical composition is smoke free, catalytic converter and O2 sensor safe while effectively removing deposits.
