NGK Spark Plug - BR6HIX - 3419

The primary advantage is the fine-wire iridium center electrode, which offers superior ignitability, leading to more efficient combustion, longer life, and improved engine performance compared to standard spark plugs.

Iridium IX spark plugs are known for their long service life, often lasting significantly longer than conventional copper or platinum plugs, typically up to 100,000 miles, though this can vary based on driving conditions and engine health.

No, it is a direct replacement only for vehicles that specifically list the NGK BR6HIX or an equivalent part number in their specifications. Always verify compatibility for your vehicle.

Yes, Iridium IX plugs are often recommended for performance applications due to their superior ignitability and ability to withstand higher combustion temperatures and pressures, but ensure it's the correct heat range for your tuned engine.

A taper cut electrode is a design modification to the ground electrode. It helps reduce the chance of the spark being 'quenched' (snuffed out) by the electrode material, leading to a more complete combustion event.

Being a genuine UK stock item implies that the product has passed NGK's quality control standards and is sourced reliably, ensuring you receive an authentic and high-quality part.

The seller offers a 60-day return policy for peace of mind. However, it is always best to confirm compatibility before purchase to avoid the need for returns.

Check if the spark plug is correctly installed and gapped (if applicable for the specific engine). Ensure the spark plug wire or coil pack is securely connected. If problems persist, the spark plug may need replacement.

Verify that the correct spark plug model is installed and that all connections are secure. A weak spark from a fouled or worn plug can cause starting issues.

Ensure the spark plug is the correct type for your vehicle and is properly installed. Inefficient combustion due to an incorrect or worn spark plug can impact fuel economy.

This may indicate an underlying engine issue such as rich fuel mixture, oil consumption, or coolant entering the combustion chamber, rather than a fault with the spark plug itself. Consult a mechanic.
