Product description
This conventional spark plug targets reliable ignition and reduced maintenance for everyday engine use, blending corrosion protection with efficient heat transfer. It fits repair and replacement needs where a conventional design is preferred, and it can be a straightforward choice for routine tuneups and marine-capable applications. If you search for a conventional spark plug for general repairs, this option covers the basics with attention to durability and suppression of misfires.
Key points
The ACDelco Gold R45S aims to cut corrosion and ignition issues through materials and seal design. A Black Onyx coating helps resist rust on the external sheath, and the nickel-chrome alloy on the center electrode adds another layer of corrosion protection. The ribbed suppressor seal extends resistance to flashover and helps reduce misfires, which matters in humid or electrically noisy environments. Keep in mind that fitment follows manufacturer specifications, so compatibility should be checked against your vehicle before ordering. ⚙️
Tech specs
- Name: ACDelco Gold R45S Conventional Spark Plug
- Material: Nickel-chrome alloy sheathing
- Battery life: Not applicable
- What’s included: Single spark plug
- Compatibility: Meets GM fit, form, and function and fits many makes and models
Benefits
This spark plug transfers heat efficiently thanks to its copper core which supports durability under normal operating temperatures, and this can help preserve electrode life. The design reduces the chance of spark flash over, so ignition consistency is more likely on older ignition systems. For maintenance routines it simplifies replacement with a conventional gasket seat style.
Who it’s for
It’s a great fit if you need a dependable, conventional spark plug for routine maintenance, value corrosion resistance, and may service marine engines occasionally. You’ll appreciate straightforward installation and materials chosen to reduce common failure modes.
It might not be a great match if you require iridium or platinum long-life electrodes for extended service intervals, or if your engine specifically calls for a different heat range than this model provides.
