Although many motorists and technicians prefer to stick with the same brand when replacing spark plugs, there's nothing on the label that limits a particular brand of plug to a particular vehicle make or model.
What are the factory spark plugs?
A quality OEM plug has a nickel-plated steel shell, as nickel is both corrosion resistant and unlikely to cause a plug to seize in the threads on the cylinder head. ... Platinum and iridium are both costly metals, and one of the easiest ways to cut costs on a spark plug is to use a low grade of platinum or iridium.
Your owner's manual will likely recommend that your Mini's spark plugs be replaced every 30,000 miles or so. That number is a bit low, so waiting even 50,000 miles should be fine if you check on their condition regularly.Jun 11, 2020
Are copper spark plugs better for performance?
A standard spark plug typically features a nickel-alloy outer material fused to the copper-core electrodes. Copper spark plugs run cooler and provide more power in performance driving situations.
What spark plugs are better than iridium?
Platinum has a great performance level compared to other regular spark plugs, but compared to iridium, the difference is clear. Iridium has a more excellent performance in igniting the air and fuel compression within the combustion chamber. This is one main reason why platinum vs. iridium performance differs.Oct 4, 2021
What's the best spark plug for performance?
Iridium – Often considered to be the best spark plugs for high performance and longevity. Iridium usually lasts 25% longer than platinum, but you guessed it, they're usually more expensive! The electrode is . 4mm and the smallest of all four.Mar 23, 2020
What type of spark plugs last the longest?
Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency.
How do you match spark plugs?
The heat range must be carefully selected for proper spark plug thermal performance. If the heat range is not optimal, then serious trouble can be the result. The optimal firing end temperature is approximately 500°C (932°F) to 800°C (1472°F).
What is better platinum or iridium spark plugs?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
What is the difference between iridium and double iridium spark plugs?
Double iridium spark plugs withstand higher temperatures and pressures during the combustion process, increasing lifespan. Double iridium spark plugs have a lifespan estimated to be up to four times that of traditional, non-precious metal plugs, and 125% that of similar platinum-based devices.
