Bosal 090-744 Spark Plugs

Introducing the BOSAL 090‑744 Spark Plug

The BOSAL 090‑744 is a high‑performance ignition component engineered for modern gasoline engines that demand precision, durability, and consistent power delivery. Designed with advanced metallurgy and an optimized electrode geometry, this spark plug delivers reliable combustion across a wide range of operating conditions.

Key Technical Features

• Electrode Material: Hardened platinum‑tipped center electrode combined with a nickel alloy ground electrode ensures long life and minimal fouling.
• Heat Range: Medium heat rating (approximately 5–6) balances spark intensity with engine temperature control, making it suitable for both street and light performance applications.
• Insulator Design: Ceramic insulator with a reinforced body resists high temperatures and electrical arcing, extending service life.
• Thread Size & Length: Standard 14 mm thread diameter with a 10 mm length, compatible with most OEM specifications for compact and mid‑size engines.
• Coating: Anti‑corrosion coating protects the metal surfaces from moisture and combustion byproducts.

Performance Advantages

The BOSAL 090‑744 delivers a consistently strong spark, which translates into smoother idle, improved throttle response, and better fuel economy. Its durable construction reduces the frequency of replacements, saving time and maintenance costs over the life of the vehicle.

Engine Compatibility

This spark plug is engineered to fit a broad spectrum of gasoline engines, particularly those found in:

• Compact cars with inline‑4 or inline‑5 configurations.
• Mid‑size sedans and hatchbacks that require reliable ignition under varying load conditions.
• Lightweight performance vehicles where spark plug longevity is critical.

Engineers recommend verifying the OEM specifications for thread size, heat range, and gap before installation to ensure optimal compatibility.

Installation Guidelines

1. Turn off the engine and allow it to cool completely.
2. Remove the old spark plug with a socket wrench or torque tool.
3. Check the gap on the new plug using a feeler gauge; adjust if necessary.
4. Screw in the BOSAL 090‑744 by hand until it is snug, then tighten to the manufacturer’s specified torque setting.
5. Reconnect the spark plug wire or coil pack and repeat for all cylinders.

Maintenance Tips

• Inspect spark plugs every 10,000–15,000 miles or as recommended by your vehicle’s service schedule.
• Keep the engine bay clean to prevent dust and debris from settling on the plug threads.
• Avoid using excessive force when tightening; use a calibrated torque wrench to prevent damage to the insulator.
