Product Details

The NGK 3530 B9EG racing spark plug is engineered for high-performance applications where precise ignition and durability are critical. This professional-grade spark plug features platinum at both the fine-wire center electrode and the ground electrode, delivering extended service life and consistent performance under demanding conditions.

Key Features:

  • Dual platinum electrodes provide superior wear resistance and gap stability
  • Fine-wire center electrode design improves ignitability and throttle response
  • Enhanced protection against plug wear and electrode erosion
  • Original equipment specification on many late model performance applications
  • Heat range 9 for high compression and forced induction engines
  • 14mm thread diameter with standard reach

Sold as a 4-pack in standard NGK packaging. The B9EG is ideal for racing and high-performance street applications requiring a colder heat range spark plug. NGK's platinum technology ensures consistent spark energy and reduced maintenance intervals compared to conventional copper core plugs.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

you have what i need at a great price

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.
