ENA set of 16 pre-gapped iridium spark plugs designed to replace 570 RE14MCC4 and fit select Dodge Ram, Chevrolet, GMC, Buick, Jeep, Chrysler, Cadillac and Saturn engines from 2000–2022.

These spark plugs are engineered for drivers and mechanics who need a full replacement set that matches factory fit and function across a long list of V8 and inline-4 applications. Built with a fine-wire iridium center electrode and delivered pre-gapped, the set simplifies installation and aims to provide consistent ignition performance across multi-cylinder engines like the 5.7L HEMI V8 and various 2.0–2.5L four-cylinders.

Which vehicles and engines will these plugs fit?

ENA provides wide vehicle coverage across GM and FCA lineups. The listing cites compatibility with Ram 1500/2500/3500 (2003–2008) V8 5.7L and multiple Chevrolet, GMC, Buick, Cadillac, Chrysler and Jeep models with 2.0L–2.5L or 5.7L–6.1L engines through model year ranges up to 2022.

• Chevrolet/GMC/Buick/Cadillac/Saturn: Cavalier, Cobalt, HHR, Malibu, Impala, Colorado, Blazer, Acadia, Envision, LaCrosse, ATS, LW1 and more (2.0L–2.5L engines).
• Reference numbers: 570 RE14MCC4, 56028374AB, AP5263 for cross-checking fitment.

How are these spark plugs different from stock units?

ENA’s plugs use a fine-wire iridium center electrode rather than a conventional copper tip, which helps concentrate the spark and can offer longer service life. They come pre-gapped to 0.051 inches to match common OEM specifications, cutting out the guesswork during installation.

• Center electrode: fine-wire iridium for focused spark delivery.
• Pre-set gap: 0.051 in to streamline installation and reduce gap errors.
• Mechanical specs: hex size 0.63 in, thread diameter 14 mm for proper seating.

What performance or maintenance benefits should I expect?

These plugs are designed to provide dependable ignition across all cylinders, helping maintain consistent starting and combustion. While every vehicle and condition differs, iridium tips typically resist erosion longer than conventional designs, which can help preserve ignition quality between service intervals.

• Consistent spark across cylinders for stable idling and throttle response.
• Durable iridium tip to slow electrode wear versus standard plugs.
• Set of 16 allows full replacement for 8-cylinder engines with an extra set available for vehicles requiring sixteen plugs.

How should I install and verify fitment before buying?

Always confirm compatibility using your vehicle’s VIN or parts lookup before purchase; improper parts can lead to poor engine performance. Installation requires the correct spark-plug socket and torque wrench to seat the plug to factory torque specs and avoid damage to threads or the electrode.

• Check VIN-based fitment tools or manufacturer cross-reference numbers.
• Use a spark-plug socket and torque wrench; tighten to OEM torque values.
• Replace plugs in cool engine conditions and inspect boots/wires concurrently.

Who this product is for: This ENA 16-piece spark plug set is intended for mechanics, fleet owners, and DIYers who need a reliable, full-set replacement for compatible Dodge, Chevrolet, GMC, Buick, Jeep, Chrysler, Cadillac and Saturn models. It is especially useful when servicing multi-cylinder engines such as HEMI V8s or when replacing plugs across a family of vehicles to maintain consistent ignition performance. The pack includes a 12-month warranty and is best purchased after confirming exact vehicle compatibility via VIN or parts cross-reference.
