Polyacrylate
Better heat, oil and chemical resistance than NBR
It is recommended for use in oil which contains load bearing additives such as EP gear oils- 4
a7tc spark plug. **Longer Plug Life** A7TC spark plugs are known for their long life and resistance to corrosion, ensuring that your engine will continue to perform well over time.
- The valve cover gasket seals the gap between the cylinder head and the valve cover, preventing oil leaks that could compromise efficiency and potentially lead to severe damage. It is held in place by a set of bolts, which not only secure the gasket but also maintain the necessary pressure for a leak-free seal.
Furthermore, iridium spark plugs are designed to withstand high temperatures and extreme conditions inside the engine. This means they are less prone to fouling and misfiring, even under intense driving conditions. This reliability makes iridium spark plugs a great choice for performance cars or vehicles that are used for towing or heavy-duty applications.
