Priced per each. A great oem quality spark plug by NGK for tuned 1.8T, 2.0T, and other fitments. Great for Audi/VW cars with K04 turbo setups and performance software. These are one heat range colder than the stock plugs. These platinum plugs last longer than copper core plugs. Pre-gapped to .028". Buy four plugs and get a free tube of anti-seize.
