Product Information

The NGK 97506 (SILZKBR8D8S) Laser Iridium Spark Plugs are 2-step colder for N54 and N20 engines and 1-step colder for N55 and S55 engines. They suggested for higher boost E85, water/meth injection, and/or upgraded turbocharger applications across all late model turbo BMW models. 

It is recommended to gap these plugs to 0.022-0.023" for all tuned N20, N54, N55, S55, N63, N63TU, S63, and S63TU applications. 

Please contact us if you have any questions about the suitability of these plugs for your BMW model.

Why opt for a colder spark plug?

Running colder spark plugs will not necessarily increase power but they may restore power if the current plugs are old and worn. Colder spark plugs are more efficient at transferring heat away from the tips of the spark plugs. Lower horsepower engines will not create as much heat, so these spark plugs may not work as effectively as the OEM option under 450whp, or they will require replacement sooner. The reason behind that is that the spark plug tips stay too cool and become less effective at burning carbon deposits off the tip of the plugs. However, keeping the spark plug tips cooler is essential for preventing misfires in higher horsepower engines.

About NGK Laser Iridium Spark Plugs 

NGK Laser Iridium spark plugs provide superior ignitability and long service life. Fine wire iridium tipped centre electrode and fine wire platinum tipped ground electrode ensures slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions.

  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties.
  • Corrugated ribs prevent flashover.
  • Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer.
  • Copper core aids in heat removal.
  • Triple seals prevent leakage.
Beware of counterfeit NGK plugs being sold at a cheaper price by other vendors. They do not offer the same performance, lifespan, and knock resistance.

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!

Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.

Took my e60 there, Jimmy was an absolute pleasure to deal with, very honest, explained everything in detail, and provided some great recommendations due to my individual circumstance. Can not recommend highly enough.
