NGK Iridium IX Spark Plug (BKR7EIX) for VW & Skoda 1.8 / 2.0 TSI - Octavia, Octavia vRS, Superb (EA888)

The NGK BKR7EIX Iridium IX spark plug is a colder heat-range (7) iridium plug widely used on Volkswagen Group 1.8 TSI and 2.0 TSI (EA888) turbo-petrol engines, and a popular choice for tuned and Stage 1/2 builds where a cooler plug is specified. Built to NGK's Iridium IX standard for a strong, stable spark under boost.

On a high-output turbocharged engine, cylinder pressures and temperatures are high. A correctly specified plug — including the right heat range — is essential for reliable ignition, resistance to pre-ignition and clean power delivery.

Iridium IX Construction

The BKR7EIX features a fine-wire 0.6 mm iridium centre electrode with a tapered ground electrode. Iridium's high melting point and wear resistance let the fine tip hold its shape under repeated heat cycles, maintaining a consistent spark across long service intervals. NGK's resistor design and ceramic insulator suppress electromagnetic interference and manage combustion heat; the plated shell resists corrosion and seizing.

Intended Application & Fitment

Used on the VW Group 1.8 / 2.0 TSI (EA888) four-cylinder engine, which uses four spark plugs — confirm the quantity required before ordering.

Commonly fitted to (where BKR7EIX is the specified plug):

• Škoda Octavia 1.8 / 2.0 TSI, Octavia vRS, Superb 1.8 / 2.0 TSI
• Volkswagen Jetta / Passat 1.8 TSI, and tuned EA888 builds running a colder plug

Important: the BKR7EIX is most commonly specified for EA888 Gen1 / Gen2 engines and tuned applications. Later Gen3 (MQB) engines often require a different plug. Use only where BKR7EIX is listed in official service or tuning documentation. We provide fitment guidance — always confirm against your exact engine.

Why Owners Choose It

• Genuine NGK Iridium IX — a proven performance heat-range plug
• Colder heat range (7) suited to boosted and tuned engines
• Strong, consistent spark under high cylinder pressure
• Long service life versus standard nickel plugs

Installation & Service

Replace at the manufacturer's or tuner's recommended interval. Pre-gapped and direct-fit; install with correct tightening torque, clean threads and proper seating. Supplied as a single spark plug.

Summary

The NGK BKR7EIX Iridium IX spark plug is a colder heat-range iridium plug for VW and Škoda 1.8 / 2.0 TSI (EA888) engines and tuned builds. Confirm engine generation, fitment and quantity before use.
