OVERSTOCKDIRECT NGK Iridium IX Spark Plugs LKR7DIX-11S 6-Pack — Iridium Tips, 3.5–3.7L V6 Fit

Premium NGK Iridium IX LKR7DIX-11S spark plugs, sold in a 6-pack, designed for reliable ignition performance and long service life in many V6 applications.

These LKR7DIX-11S spark plugs (stock 93175) combine an iridium fine-wire center electrode with a taper-cut ground tip and a ceramic insulator to deliver consistent spark, reduced wear, and predictable gap control. They are commonly used as original-equipment or direct-replacement plugs for a wide range of 3.0–3.8L and 3.5–3.7L V6 gasoline engines from Acura, Honda, Hyundai, Kia, Dodge, Chrysler, Jeep, Ram, Volkswagen, Mitsubishi, Genesis and others. Each plug features a 5/8" hex, a 1.043" reach, a 0.044" pre-gap, and a built-in resistor to help suppress electrical interference.

Which vehicles and engines fit these LKR7DIX-11S plugs?

These plugs are compatible with many late-model V6 vehicles. They cover a broad set of OEM applications across North American and Asian marques; always verify against your vehicle’s engine code, year, and cylinder count before ordering.

• Common Acura/Honda fits: RDX, RL/RLX, TL/TLX, TSX, ZDX, Accord, Odyssey, Pilot, Ridgeline, Crosstour (3.5–3.7L V6 ranges).
• Chrysler/Dodge/Ram/Jeep fits: 200/300/Pacifica/Avenger/Charger/Challenger/Grand Caravan/Durango/Grand Cherokee/Wrangler and 3.6L Pentastar engines.
• Also fits select Hyundai, Kia, Mitsubishi, Volkswagen Routan and Genesis V6 engines (3.0–3.8L).
• Confirm engine displacement and OEM part cross-reference before installation.

How does the iridium design affect durability and performance?

Iridium’s high melting point lets manufacturers produce a very fine center electrode, which lowers required voltage and sharpens the spark. The result is improved ignitability compared with larger electrodes and extended service life under normal operating conditions.

• Fine-wire iridium center electrode for stable ignition and lower voltage needs.
• Taper-cut ground electrode improves flame kernel growth and combustion efficiency.
• Copper core for heat transfer and thermal stability.
• High-quality ceramic insulator reduces misfires and resists fouling.

What are the technical specs I should know before buying?

Key dimensions and construction details matter for fit and function: this NGK part has a 12.0 mm thread diameter, 26.5 mm (1.043") reach, and a 5/8" (16 mm) hex for installation. The electrical resistor and pre-gap are factory set to match many OEM ignition systems.

• Part number: LKR7DIX-11S (stock 93175); sold as a 6-pack.
• Pre-gap: 0.044" (1.1 mm); resistor 5000 ohms for radio/noise suppression.
• Center electrode: iridium tip on copper core; ground tip: taper-cut nickel.
• Seat type: flat; reach: 1.043" (26.5 mm); hex size: 5/8" (16 mm).

How should I handle installation and routine replacement?

Install with the correct torque and a clean mating surface; NGK-style plugs often call for a crush washer to ensure a proper seal. Replace plugs as part of routine maintenance intervals or if misfire, poor fuel economy, or rough idle appears.

• Use a torque wrench and follow vehicle manufacturer torque specs for 12 mm plugs with 1.043" reach.
• Check and match the factory gap; these come pre-gapped but verify before fitting.
• Replace in complete sets for multi-cylinder engines to maintain consistent firing.
• Inspect ignition coils and wiring while servicing plugs to prevent premature failure.

Who is this for: Mechanics, DIY enthusiasts, and fleet owners who need a reliable, OEM-quality replacement spark plug for many V6 gasoline engines will value the NGK Iridium IX LKR7DIX-11S 6-pack from OVERSTOCKDIRECT. If your vehicle’s service manual lists the equivalent NGK part or specifies an iridium fine-wire plug for improved longevity and steady performance, this set provides a cost-effective way to refresh all cylinders at once. Always confirm part compatibility with your engine code, model year, and local service recommendations before purchase.
