Genuine NGK Iridium IX BKR8EIX x 4  S/P for VW Audi EA113 EA888 Nissan R32 33 34 Toyota MK4 Opel  & Vauxhall

The NGK BKR8EIX spark plug is a very cold heat range plug (the "8" indicates it's colder than the BKR7EIX) and is almost exclusively used as a performance upgrade for highly modified or aggressively driven vehicles, rather than a factory original equipment plug.

It is overwhelmingly popular for, and commonly sold as an upgrade for, performance vehicles in the Volkswagen Audi Group (VAG) stable:

• Volkswagen & Audi 2.0L Turbocharged Engines:
• EA113 (Found in models like the Golf GTI MK5, Golf R MK6, Audi S3 8P)
• EA888 Gen 1 & Gen 2 (Found in models like the Golf GTI MK6, Audi A4 B8, A5)
• Note: This plug is typically not for the newer EA888 Gen 3 (MQB) engines (Golf GTI MK7/R).

It is specifically recommended for applications that produce significantly more heat than stock, such as:

• Vehicles running Stage 2, Stage 3, or higher ECU tunes.
• Cars with larger turbochargers or very high boost pressure.
• Vehicles running performance fuels like Ethanol blends (E85/E30).
• Cars used for heavy track duty or road racing.

Due to its universal size, it can also be an upgrade for other high-performance turbocharged or high-heat engines, including some:

• Mitsubishi (Evo)
• Nissan (SR20DET, RB series)
• Toyota (2JZ-GTE, 2ZZ)

In summary, the BKR8EIX is not a factory plug for most cars; it is a critical cooling upgrade for seriously tuned 2.0T VAG engines and other high-boost performance platforms.

Always check with your engine tuner or a reliable parts guide for your exact car and modification level before installing a colder plug.

The NGK BKR8EIX spark plug is a high-performance iridium plug that is a "colder" heat range than many standard spark plugs. This makes it particularly popular for use in modified and high-performance cars, where the engine is running at higher temperatures and pressures.

Some of the most common applications for the NGK BKR8EIX spark plug include:

• Volkswagen and Audi (VAG) Group cars: This is a very popular plug for modified VW and Audi models with the EA113 and EA888 2.0T FSI and TSI engines, such as the Volkswagen Golf GTI (MK5 and MK6), Golf R (MK6), Audi S3 (8P), and Audi A4/A5. It is often used as an upgrade for "Stage 2" and "Stage 3" tunes where the engine's performance has been significantly increased.
• Nissan and Toyota performance cars: The BKR8EIX is also used in a variety of performance models from these Japanese manufacturers, including the Nissan Skyline (R32, R33, R34) with RB25DET/RB26DETT engines, Nissan 200SX (S13, S14) with SR20DET engines, and Toyota Supra (MK4) with 1JZGTE/2JZGTE engines. It's also used in some Toyota Corolla and MR-2 models with the 2ZZ-GE engine, particularly in high-heat applications.

·        Opel/Vauxhall performance cars: Some performance models like the Corsa VXR and Astra VXR with Z20LEx engines also use these plugs, especially in highly modified applications.

·        Other performance and race cars: Due to its cold heat range and iridium construction, the BKR8EIX can be a good choice for a wide range of other high-performance and race car applications, from Mitsubishi Lancer Evolution models to various BMW, Mazda, and Subaru cars.

It's crucial to note that using a colder plug like the BKR8EIX is generally only recommended for tuned or high-performance engines. For a stock engine, the factory-recommended heat range is typically the best choice. Always consult your vehicle's owner's manual or a specific performance parts guide to confirm the correct spark plug for your car and its level of tune.
