NGK Spark Plug Sets | 22R / 22RE / 22R-TE (1984-95 4Runner / 1981-95 Pickup)

NGK Iridium IX / V-Power Nickel Spark Plug Sets

For 1984–1995 Toyota 4Runner and 1981–1995 Toyota Pickup with 22R, 22RE, or 22R-TE four-cylinder engines

Overview

Both options are factory pre-gapped to 0.032 in (0.8 mm) for the listed stock Toyota 22R-family engine applications. NGK V-Power Nickel and Iridium IX arrive with the same manufacturer-preset electrode gap; the iridium electrode technology does not require a different preset gap. Choose V-Power Nickel for conventional OE-style maintenance or Iridium IX for fine-wire iridium electrode technology. Each configuration includes four resistor-type spark plugs for one Toyota 22R, 22RE, or 22R-TE engine.

Key Features

• Factory pre-gapped — both options: V-Power Nickel and Iridium IX each come preset to 0.032 in (0.8 mm), matching the nominal 0.8 mm factory specification for the supported stock engines.
• V-Power Nickel: Nickel-alloy V-groove center electrode with a copper core for stock-style ignition maintenance.
• Iridium IX: Fine-wire iridium center electrode with improved resistance to electrode wear.
• NGK resistor construction: Corrosion-resistant shell plating and gasket-seat design.
• Complete four-plug set: One selected set supplies all four spark plugs for a supported four-cylinder engine.

Vehicle Fitment

Fitment Notes

• Engine requirement: Factory Toyota 22R, 22RE, or 22R-TE four-cylinder gasoline engine.
• Factory turbo applications: 22R-TE fitment covers 1986–1987 Toyota 4Runner and 1986–1988 Toyota Pickup.
• Excluded engine: Does not fit the 3VZ-E V6.
• Factory pre-gap: Both NGK plug options have a nominal 0.8 mm factory gap (commonly rounded to 0.032 in). This matches the published stock 22R / 22RE / 22R-TE gap; modified engines, nonstandard ignition setups, or plugs with altered or damaged gaps require individual specification review.

Which Spark Plug Is Right for You?

V-Power Nickel — Best for Factory-Style Service & Value

Choose V-Power Nickel for conventional copper-core, nickel-alloy construction and NGK's V-grooved center electrode. It keeps routine maintenance straightforward at a lower purchase price.

Iridium IX — Best for Premium Fine-Wire Construction

Choose Iridium IX for its fine-wire iridium center electrode and improved electrode-wear resistance over conventional nickel plugs. Its ground electrode remains nickel alloy rather than platinum-tipped.

DENSO Spark Plug Set — Best for U-Groove or Twin-Tip Alternatives

NGK and DENSO both offer established spark plug designs; neither brand is universally better. NGK V-Power has a V-grooved center electrode, while DENSO Standard U-Groove grooves the ground electrode. DENSO Iridium TT pairs an iridium center tip with a platinum ground tip, compared with the iridium-and-nickel design of NGK Iridium IX.

Our Recommendation: Choose V-Power Nickel for conventional stock-style maintenance or Iridium IX for NGK's fine-wire iridium design. Consider DENSO Iridium TT if dual-precious-metal construction is your priority.
