NGK Spark Plug 94290 – For vehicle make(s) Porsche, Audi
Manufacturer Part Number: 94290
Description
The NGK Spark Plug 94290 is engineered to provide optimal performance in your Porsche or Audi vehicle, ensuring that your engine runs smoothly and efficiently. As a critical component, the spark plug ignites the air-fuel mixture in the combustion chamber, driving the piston down and converting that energy into horsepower. When spark plugs wear out, they can lead to power loss, hesitation, misfires, and poor startup performance. NGK spark plugs are manufactured to OE specifications, offering premium-grade construction trusted by professionals.
Standard copper tip spark plugs typically require replacement every 10,000 to 30,000 miles, while iridium plugs can last upwards of 60,000 miles, and platinum plugs are rated for approximately 100,000 miles. To ensure the best performance from your engine, it’s essential to follow the part numbers listed in your owner’s manual and use dielectric grease for a secure electrical connection.
