Spark Plug 21 7905 Electronic 7900 [Bosch] ( Made in India ) (0242229656) (0242235663)

STANDARD IGNITION: BOSCH Nickel Spark Plugs (0242229656 / 0242235663) – Reliable Performance for Older Vehicles.

RESTORE IGNITION RELIABILITY. END ROUGH IDLE. GET THE OE-QUALITY NICKEL PLUGS FOR ROUTINE TUNE-UPS.

The Bosch spark plugs with these part numbers (0 242 229 656 - Bosch Code: 7905 / WR8DC+ and 0 242 235 663 - Bosch Code: 7900 / WR7DC+) are widely used Nickel-Copper core plugs designed for older, non-advanced, gasoline engines from the 1980s and 1990s, common in the Egyptian market (e.g., various models from older Hyundai, Kia, Fiat, and classic European makes). They are often distinguishable by their larger 20.8mm Hex size.1

These are standard Nickel Alloy plugs with a Copper Core (Super Spark Plug line) offering superior heat dissipation, anti-fouling resistance, and a reliable spark. They are essential for maintaining engine performance and economy over shorter, routine service intervals (typically 20,000–30,000 km).

CORE SPECS: Nickel/Copper Core for Older PFI Engines

The primary difference between the two codes is the Heat Range (WR8DC+ is slightly "colder" than WR7DC+), reflecting a variation in thermal requirements for different engines within the same platform (e.g., small differences in compression ratio or application).

WHY BOSCH NICKEL PLUGS ARE YOUR MUST-BUY NOW

You are choosing the assurance of a global OE supplier for cost-effective, routine maintenance.

1. Correct Heat Range (Critical): Choosing the correct heat range (WR7 vs. WR8) is vital. BOSCH provides OE-specified thermal characteristics to prevent pre-ignition (knock) in high heat and fouling in city driving.

2. Prevents Fouling & Overheating: The Copper Core rapidly dissipates heat, and the nickel electrodes are designed to quickly reach the self-cleaning temperature, reducing carbon buildup that causes misfires.

3. OE-Spec Reliability: BOSCH guarantees precise dimensions, ensuring a correct fit into the cylinder head threads and maintaining the required electrode gap (though a final check is always recommended).

4. Affordable Routine Care: As standard Nickel plugs, these offer the reliable ignition required by the manufacturer at the most affordable price point, making regular tune-ups accessible.

OPTIMIZE YOUR IGNITION SYSTEM.

Spark plugs are sold individually but 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 WR7DC+ (7900) or WR8DC+ (7905) heat range required.
