This set of eight plugs is calibrated to run two heat ranges colder than many stock configurations, making them suitable for boosted or nitrous applications where heat management matters. The non-projected tip is designed with power adders in mind, helping ignition paths stay efficient under demanding conditions.\u003c\/p\u003e\n\n\u003ch2\u003eWhy these plugs stand out\u003c\/h2\u003e\n\u003cp\u003eDesigned to balance performance with affordability, the BR7EF pairings emphasize dependable starts and consistent combustion. A V-grooved center electrode promotes ignitability and reduces quenching, while the 98% pure copper core improves heat dissipation. The combination of a high-grade alumina silicate ceramic insulator and a robust ceramic-to-metal bond contributes to long-term reliability even under elevated operating temperatures.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eV-Power Nickel\/Copper design offers a cost-conscious alternative for usual maintenance cycles.\u003c\/li\u003e\n  \u003cli\u003eTwo heat ranges colder than stock helps manage heat in boosted or nitrous setups while preserving ignition stability.\u003c\/li\u003e\n  \u003cli\u003e90-degree V-Groove electrode positions flame travel for broader flame expansion and smoother burn.\u003c\/li\u003e\n  \u003cli\u003eFactory pre-gapped to .028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Michigan Motorsports","offers":[{"title":"Default Title","offer_id":42474576117845,"sku":"B0C54BJCVP","price":59.66,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/image-1_e9169841-5d9f-4c73-bf7f-4586bc794549.jpg?v=1778251210","url":"https:\/\/plentytorque.co.uk\/products\/ngk-br7ef-3346-spark-plugs-set-of-8-for-ls-engines-michigan-motorsports","provider":"PlentyTorque","version":"1.0","type":"link"}
