In the past decade, Gasoline Direct Injection engines have become extremely popular with both domestic and import auto manufacturers. Compared to conventional fuel injection, GDI can deliver improved fuel efficiency, more power from smaller engines, and reduced emissions at low load. That’s great! But the popularity of GDI engines has brought back an old service issue – carbon deposits that can rob drivers of horsepower, gas mileage, and smooth operation. CRC has created a GDI carbon deposit solution that allows you to tackle the problem quickly, easily, and at a very reasonable cost. CRC GDI IVD Intake Valve & Turbo Cleaner is an aerosol spray that’s applied through the engine’s air intake or throttle body and delivered directly to the backs of the GDI intake valves. CRC GDI Valve & Turbo Cleaner contains the highest concentration of PEA available on the market to provide the fastest, most thorough chemical cleaning available. A single application removes up to 46 percent of carbon deposits in the first 60 minutes. First, just as you would with any product, read the entire product label before using, so you can understand the instructions and the safety guidelines. Next, warm up the engine. CRC GDI Valve & Turbo Cleaner requires a period of heat soak to work, so you want to start with an engine that’s fully warmed up. Locate the throttle body or air intake and spray product directly through the throttle body. If the throttle body is not easily accessible, spray PAST the mass air flow sensor. But do not spray into the mass air flow sensor assembly. You can also remove the air flow sensor assembly and spray where the sensor is mounted. If the vehicle is turbocharged, you can remove the boost sensor in the charge pipe and spray into the pipe. If it’s easier you can also spry into the vacuum port. Lift the PermaStraw dual-action spray system and lock it into place…. with the engine running at 2000 RPM, spray in short bursts until the can is empty. Once the can is empty, rev the engine 2 to 3 times, but tell them not to exceed 3500 RPM. Run at idle for one minute and then turn the engine off. Reassemble the air intake system and let the engine heat soak for a full hour. The heat soak is critical, so be patient, and let the CRC GDI Valve & Turbo Cleaner do its work. After the hour is up, restart the engine and drive at highway speeds for at least 10 minutes. And remember, as our test show the maximum benefit is achieved when the vehicle is driven regularly over the next several days. So, let your customer know they should drive their car regularly over the next week or so. If you have a vehicle with severe carbon buildup, CRC GDI Valve & Turbo Cleaner can even be used in successive treatments. Just have your customer drive about a thousand miles before a second treatment, in order to get the full benefit of the first treatment.
