Precision OEM Fit & Sealing
Manufactured to strict OE standards with a dimensional tolerance of ±0.05mm, ensuring a perfect match with the cylinder head spark plug tube. Effectively eliminates oil leaks and maintains stable engine compression.
High-Performance Rubber Material
Constructed with premium FKM (Fluorine Rubber), offering exceptional resistance to high temperatures (-30°C to +200°C), engine oils, and aging. It remains flexible and durable in the harsh under-hood environment, preventing hardening and cracking over time.
Long-Lasting Performance
Optimized sealing lip design ensures consistent, reliable sealing even after prolonged use. This prevents issues like spark plug carbon buildup, ignition misfires, and rough idling caused by worn seals, reducing maintenance costs.
Direct Replacement & Easy Installation
1:1 replica of the original part for a hassle-free installation. No modifications are required, making it an ideal replacement for scheduled engine maintenance and repairs.
This seal is installed at the spark plug tube opening on the valve cover to prevent oil from seeping into the spark plug bore.
A failed seal can cause oil to contaminate the spark plugs, leading to reduced ignition efficiency, engine hesitation, and even damage to the catalytic converter.
It is highly recommended to replace these seals when servicing the valve cover gasket or changing spark plugs.
Replace all seals (4/6/8 pcs, depending on engine cylinder count) at once to prevent repeated leaks and ensure long-term engine health.
