NGK BCR8ES (5430) Copper Core Spark Plugs Set — The Ultimate Alternative to Discontinued Ford 1120834 🔧🏁🇬🇧
Brand New Factory Stock — Essential for Ford RS Turbo CVH & Cosworth YB Engines — Traditional Copper Core
Attention all Fast-Ford owners, tuners, and engine builders! Now that Ford in their wisdom have officially discontinued the legendary RS Turbo CVH / Cosworth YB spark plug (Part Number: 1120834 / AGPR071C), the classic car community has lost its go-to factory plug.
Thankfully, engine builders and leading Ford specialists have pinned down the absolute best alternative on the market to fill the void: the NGK BCR8ES (Stock Code: 5430).
Traditional Copper Core: Modern precious-metal plugs (like Iridium or Platinum) sound fancy, but classic turbocharged Ford heads thrive on the superior thermal conductivity and raw electrical grounding of a heavy-duty, traditional copper core. It ensures a crisp, healthy spark under immense cylinder pressures.
Built for Big Boost: These plugs are heavily favored for highly tuned, high-pressure setups. They are highly suitable for high-boost Cosworth YBs and RS Turbos when gapped down carefully to 20 thou (0.5mm), preventing spark blow-out.
Perfect Heat Range: Engineered to manage the intense thermal demands of old-school turbochargers, saving your pistons and valves from dangerous detonation and pre-ignition.
💎 Status: 100% Brand New & Individually Boxed. Sourced fresh from the factory, these plugs are pristine, un-gapped, and feature immaculate threads.
📸 Please review the high-resolution listing photographs carefully to satisfy yourself with the exact part numbers, packaging, and authentic NGK build quality before purchasing.
📮 Shipping Service: Dispatched via Royal Mail Tracked 48 (completely free to you, fully tracked from door to door for complete peace of mind).
⚡ Upgrade Available: Got a weekend track day, mapping session, or car show looming? You can easily upgrade to Royal Mail Tracked 24 at checkout for rapid delivery.
🕒 Dispatch Time: Same-day dispatch for all orders finalized before our 2 PM weekday cut-off. Orders completed past this time or over the weekend will be securely packaged and posted on the very next available working day.
📦 Bulletproof Packaging Protection: I know how fragile spark plugs are. If a plug gets dropped on a concrete floor during transit, the ceramic insulator can develop hairline fractures that cause terminal engine misfires. I never throw spark plugs loose into a thin paper envelope. Your set will be bundled together, wrapped in a thick, multi-layer protective cushion of shock-absorbent bubble wrap, and shipped inside a rigid cardboard mailing box to guarantee they arrive at your garage in absolutely flawless condition.
