BOSCH Iridium Spark Plug 0242236571 / FR7KI332S for Citroën Ignition System

BOSCH Iridium Spark Plug 0242236571 / FR7KI332S

The BOSCH Iridium Spark Plug 0242236571, also identified by the part number FR7KI332S, is a high‑performance ignition component designed for modern gasoline engines. It features a single electrode configuration and is engineered to deliver reliable combustion across a wide range of operating conditions.

Key Technical Specifications

• Electrode Material: Iridium – offers superior wear resistance, higher spark energy, and improved thermal stability compared to conventional copper or platinum‑copper alloys.
• Number of Electrodes: 1 (single‑electrode design)
• Thread Size: M14 x 1.25 mm – compatible with most European and American gasoline engines.
• Heat Range: Medium to high – suitable for engines that require efficient heat dissipation while maintaining optimal spark strength.
• Recommended Engine Types: Petrol engines up to 2.0 L displacement, including models from Citroën, Audi, BMW, Mercedes‑Benz, Volkswagen, and many others.

Performance Benefits

The iridium core provides a tighter spark gap tolerance, which translates into:

• Enhanced Fuel Efficiency: A more precise ignition leads to better fuel atomization and combustion, reducing fuel consumption.
• Lower Emissions: Efficient combustion minimizes unburned hydrocarbons, contributing to cleaner exhaust gases.
• Improved Engine Response: The high‑energy spark improves throttle response and reduces hesitation during acceleration.
• Extended Service Life: Iridium’s resistance to corrosion and wear means the plug can last up to 120,000 km in many applications, outperforming standard copper plugs.

Installation Guidance

Installing the BOSCH FR7KI332S is straightforward for technicians familiar with spark plug replacement:

1. Warm up the engine to operating temperature to avoid thermal shock.
2. Remove the old spark plug using a spark plug socket and ratchet, ensuring no cross‑threading.
3. Check the spark plug gap with a digital gapping tool; adjust if necessary to match the manufacturer’s specification (typically 0.7–1.2 mm).
4. Screw in the new iridium plug by hand until it is snug, then torque to the specified value (usually 140 N·m for most engines). Avoid over‑tightening.
5. Reconnect the spark plug wire or coil pack and verify proper operation before driving.

Compatibility Overview

The FR7KI332S is an OEM replacement for a wide array of vehicles. Below are representative models that commonly use this part number:

• Citroën: C4, C5, Berlingo, and various diesel‑gasoline hybrids.
• Audi: A3, A4, A6, Q3, and Q5 models with petrol engines.
• BMW: 1 Series, 3 Series, and 5 Series equipped with 1.8‑2.0 L gasoline units.
• Mercedes‑Benz: C-Class, E-Class, and GLC models featuring petrol engines up to 2.0 L.
