Benefits of 21443-3C700 OIL SEAL
Choosing this specific sealing unit is vital for protecting your vehicle’s transmission and high-performance drivetrain from oil soak. Because Lambda II engines utilize high oil pressures for their variable timing systems, selecting a premium seal ensures that no oil bypasses the rear flange, preventing slipping and contamination in the Transmission System. Proper crankcase ventilation is key; therefore, we strongly recommend browsing our Premium Oil Filters to maintain optimal internal engine pressure.
Check Engine Fitment Verification
The Lambda engine series has undergone several rear-seal revisions for different GDI and MPI configurations. To ensure the 21443-3C700 OIL SEAL is the perfect fit for your specific crankshaft housing, please contact us for professional verification using your chassis number.
