UPGRADED IGNITION: BOSCH Double Electrode Spark Plug (0242229654 / 0242235668) – Enhanced Nickel for Opel/Renault/VAG.

RESTORE SMOOTH ENGINE OPERATION. END FOULING. GET THE DOUBLE NICKEL PLUG FOR RELIABLE, CONSISTENT SPARKING.

The spark plugs with the part numbers 0 242 229 654 (Bosch Code: 7404 / FLR8LDCU+) and 0 242 235 668 (Bosch Code: 7402 / FR7LD+) are Double Electrode (Double Nickel) plugs designed for a wide range of older to mid-generation European vehicles, including those from Opel (Astra G/H, Corsa), Renault (Clio, Twingo), and VAG/Audi. These engines (often 1.4L to 2.0L PFI) benefit from the double ground electrode design which improves ignition reliability and extends service life beyond standard single-electrode plugs.

This is a premium Nickel/Copper core plug line from BOSCH (Made in China/India under German quality control), ensuring excellent heat transfer and anti-fouling characteristics, which is crucial for urban driving in Egypt.

KEY DIFFERENCE: 0242229654 (FLR8LDCU+) vs. 0242235668 (FR7LD+)

The difference is primarily in the Heat Range and the Electrode Tip/Gap:

• 0 242 229 654 (FLR8LDCU+): Colder heat range (8). Often used in engines running hotter (e.g., higher compression or more sustained load) and is a slightly more advanced version of the design.

• 0 242 235 668 (FR7LD+): Hotter heat range (7). Often used in engines running cooler or those with a higher tendency toward fouling (stop-and-go city traffic).

Both feature 2-4 ground electrodes (Double/Multiple Nickel) and a 16mm Hex size (though some older VAG versions used a 20.8mm Hex).

THE CORE SPECS: Nickel Alloy with Enhanced Durability

These plugs are designed for reliable, durable ignition over an extended service life (approx. 30,000–45,000 km).

WHY BOSCH DOUBLE NICKEL IS YOUR MUST-BUY NOW

You are choosing a dependable, mid-range upgrade that balances cost with durability and performance.

1. Guaranteed Consistent Spark: The double-electrode design is highly robust and ensures consistent firing, eliminating rough idling and hesitation better than single-electrode plugs.

2. Extended Service Life: The multi-electrode design and heat-resistant construction provide a service life that is significantly longer than standard copper plugs, providing a great value-for-money upgrade.

3. OE-Spec Reliability: BOSCH guarantees precise dimensions and heat range, ensuring a correct, safe fit into the cylinder head.

4. Excellent for Urban Driving: The combination of proper heat range and electrode stability makes these plugs excellent for engines that spend a lot of time in stop-and-go traffic where fouling is a risk.

OPTIMIZE YOUR IGNITION SYSTEM.

Spark plugs must be replaced as a full set (4 plugs) for balanced engine operation.

Crucial Check: Verify the original plug code in your vehicle (or owner’s manual) to determine the exact FR7LD+ (7402) or FLR8LDCU+ (7404) heat range required.
