TRQ Spark Plug Kit 7 Piece Iridium Compatible with 2002-2004 Nissan

Our review of the TRQ Spark Plug Kit finds it best suited for DIY motorists and independent mechanics who need a complete ignition refresh for V6 3.3L naturally aspirated Nissan Frontier and Xterra models from the early 2000s. The single biggest reason to consider this kit is convenience: it bundles six iridium spark plugs with a matched spark plug wire set so the plugs and wires are designed as direct-fit replacements and require no modifications. That combined approach can save time during a tune-up and helps restore ignition consistency when the original parts are worn.

Key Features

• Complete kit: Includes one spark plug wire set and six iridium spark plugs, so users get all ignition components needed for a full replacement in a single purchase.
• Direct-fit design: Application specific design means no modifications are necessary, reducing installation time and fitment guesswork for the specified Nissan models.
• Iridium plugs: Iridium construction is intended to provide consistent spark performance and longer life compared with conventional electrodes.
• Tested for performance: TRQ reports fit, lab, and road testing to match stock specifications, which supports reliable function when replacing worn parts.
• Reference compatibility: Multiple reference numbers are supplied to help verify fitment against OEM catalogs and compatibility charts before purchase.
• Installation support: TRQ provides extensive DIY video resources so buyers can view installation steps before starting the job.

Who It's For

This kit is aimed at owners of 2002-2004 Nissan Frontier V6 3.3L and 2003-2004 Nissan Xterra V6 3.3L who prefer to tackle maintenance themselves or who want to hand a complete, matched set to their mechanic. The bundled wire set plus six plugs makes it practical for a single-shop tune-up or a DIY weekend repair.

It is not ideal for vehicles outside the listed fitment or for users who need custom or high-performance ignition parts beyond a direct stock-equivalent replacement. Buyers who require custom gap settings should check plugs on arrival, as some users report occasional gap or performance variability with replacement iridium plugs.
