Wynn's Direct Injection Valve Cleaner High-Strength Foam 500ml - Code W28879
The professional-grade Wynn's Direct Injection Valve Cleaner (Product Code: W28879) is an advanced high-potency chemical foaming treatment engineered to rapidly, safely, and thoroughly eliminate hardened carbon scale and biological soot deposits from the air intake manifold, intake valves, valve seats, and internal combustion chambers. Developed specifically for direct injection power units prone to severe intake induction fouling, this flushing agent restores proper volumetric air mass flow and recaptures original engine compression parameters.
Design Details and Functionality
In modern direct injection internal combustion engines (both gasoline and diesel), fuel is atomized directly within the cylinders, bypassing the intake valves entirely and preventing the natural fuel-washing effect. This design leads to heavy accumulation of performance-robbing lacquer and sticky oil soot along the intake lines. The highly persistent foam matrix of this treatment settles directly onto the hot intake valve surfaces and inside the EGR valve modules, chemically dissolving hardened deposits without damaging sensitive seal materials. By opening restricted cross-sections, it secures unhindered airflow and smooth engine operation across all speed ranges. On diesel platforms, it contributes downstream to fuel system maintenance by supporting cetane enhancement, improving fuel ignition parameters, and significantly suppressing tailpipe soot and black smoke emissions.

Pre-Application Checks & Technical Constraints
CRITICAL STRUCTURAL COMPATIBILITY CONSTRAINT: Do not apply to vehicles where the intercooler assembly is integrated directly into the intake manifold structure.
- DPF Assessment (Diesel Platforms): Check the soot saturation level and differential pressure metrics of the Diesel Particulate Filter. If the filter mass density limits exceed 50% or if differential pressures register too high, clean the filter first using Wynn’s DPF On Car fluid.
- Manifold Inspection: In cases of extreme macroscopic carbonaceous crust buildup within the induction manifold, a preliminary manual teardown and mechanical cleaning is strongly recommended before starting the chemical spray cycle.
- Powertrain Status: Ensure the vehicle engine has reached standard, optimal operational temperature ranges before starting the spray application.
- Detonation / Backfire Management: If severe engine knocking, heavy pinging, or intake backfires trigger during execution, stop spraying immediately. Let the engine settle at idle speed for 3 to 4 minutes before carefully resuming. If hard knocking persists, the intake is overly fouled and demands manual cleaning.
Workshop Application Protocols
| DIESEL ENGINE PROCEDURE |
GASOLINE ENGINE PROCEDURE |
1. Stabilize the engine speed at a steady 1,500 – 1,800 RPM.
2. Introduce the spray probe directly into the air intake manifold port positioned downstream of the intercooler unit.
3. Deliver short spray bursts at 1-2 second intervals, allowing engine RPM levels to stabilize completely between pulses.
4. Every 10 consecutive erogations, pause application and let the engine idle smoothly for 3–4 minutes.
5. Repeat steps 3 and 4 continuously until the contents of the can are completely consumed.
6. MANDATORY POST-TREATMENT MAINTENANCE: Perform a complete internal engine oil system flush, then immediately complete an engine oil change and install a new oil filter element.
7. Perform a road test under light loading parameters, ensuring the engine does not exceed 2,500 RPM for the first 10 minutes of travel. |
1. Stabilize the engine speed at a steady 2,500 – 3,000 RPM.
2. Apply the chemical agent directly through the primary entry port of the intake manifold.
3. Deliver short spray bursts at 1-2 second intervals, allowing engine RPM levels to stabilize completely between pulses.
4. Every 10 consecutive erogations, pause application and let the engine idle smoothly for 3–4 minutes.
5. Repeat steps 3 and 4 continuously until the contents of the can are completely consumed.
6. MANDATORY POST-TREATMENT MAINTENANCE: Perform a complete internal engine oil system flush, then immediately complete an engine oil change and install a new oil filter element.
7. Complete a comprehensive road test, operating the power plant smoothly across its full RPM spectrum. |
