ENA Iridium Platinum Spark Plugs for 3.5L/3.6L V6 — Pack of 6, Pre-Gapped 0.043" for Dodge Chrysler Jeep Honda Acura

ENA Iridium Platinum Spark Plugs (pack of 6) are high-durability, pre-gapped replacement plugs designed for many 3.5L and 3.6L V6 engines from 2011–2026.

This set of six iridium-tipped spark plugs from ENA is built to match OEM fitment and deliver consistent ignition performance across a broad range of Dodge, Chrysler, Jeep, Ram, Honda, Acura and Volkswagen models. Each plug is pre-gapped to 0.043 inches and uses a fine iridium center electrode for long life, better ignition stability, and easier starting compared with conventional plugs. The kit includes compatible reference numbers XP5701, 7751, 9407, SP149125AF, and SP149125AD for quick cross-referencing with factory parts.

Which vehicles will these ENA spark plugs fit?

These spark plugs are engineered for many V6 engines from the 2010s and early 2020s. Fitment covers multiple makes and models that use 3.5L or 3.6L V6 engines, including minivans, sedans, SUVs, trucks and commercial vans.

• Dodge & Chrysler: Grand Caravan, Durango, Charger, Challenger, 300, Pacifica, Town & Country, 200, Voyager (various years listed).
• Jeep & Ram: Grand Cherokee, Wrangler, Gladiator, Ram 1500 and ProMaster series across supported years.
• Honda & Acura: Odyssey, Accord, Pilot, Ridgeline, Passport, MDX, TLX, TL, RLX and more when using compatible 3.5L engines.
• Volkswagen Routan and other listed models where the manufacturer specifies the matching reference numbers.

How do these plugs improve reliability and maintenance?

Iridium center electrodes provide a harder, longer-lasting firing point than standard copper tips. The pre-set 0.043" gap reduces installation adjustments, helping you finish a tune-up faster while maintaining consistent spark under varied driving conditions.

• Iridium tip for extended wear and steady spark quality.
• Pre-gapped to 0.043 inches to save installation time and ensure proper clearance.
• Hex size and thread dimensions match OEM specifications for snug fitment.
• Pack of six covers full replacement needs for most V6 cylinder banks.

What are the technical specifications I should know before buying?

This ENA set is specified for V6 applications and includes the key physical and electrical details technicians use to confirm compatibility. Review these specs against your vehicle’s service manual or parts lookup to verify fit.

• Center electrode material: Iridium for superior durability.
• Standard gap: 0.043 inches (pre-gapped out of the box).
• Thread diameter: 12 mm; hex size: 0.47 inches for wrench selection.
• Package: set of 6 spark plugs and a 12-month warranty from ENA.

How should I install and check these plugs?

Installation follows the same routine as other threaded spark plugs: remove ignition coils, extract old plugs, inspect threads and cylinder condition, then hand-start and torque the new plugs to factory specs. Because these plugs arrive pre-gapped, confirm the gap and torque values before finalizing installation.

• Always verify vehicle-specific torque and thread engagement before tightening.
• Inspect spark plug wells and ignition coils for wear or oil contamination.
• Use a torque wrench and follow manufacturer tightening sequence.
• Clear any debris from the well to avoid cross-threading or contamination.

Who is this for: The ENA Iridium Platinum Spark Plug pack of six is intended for mechanics, DIY owners, and fleet managers who need an affordable, long-life replacement for common 3.5L and 3.6L V6 engines across Dodge, Chrysler, Jeep, Ram, Honda, Acura and VW Routan lineups. If you want OEM-style fitment, reduced maintenance time with pre-gapped plugs, and a durable iridium electrode for sustained performance, this set is a practical choice.
