These six Champion iridium spark plugs are specified to match the original-equipment design for Jeep Wrangler 3.6L V6 engines built between 2012 and 2017. They come with the correct plug type (RER8ZWYCB4 equivalent) and a factory-set gap around 0.043–0.044 inches so you can swap them in without extra adjustments for most installations. Packaged as a complete set, they’re meant to provide a straightforward replacement when your Wrangler needs new ignition components.

Will these spark plugs fit my Jeep Wrangler 3.6L V6 from 2012–2017?

Yes — this six-pack is designed as a direct replacement for the 3.6L V6 Wrangler across model years 2012 through 2017. The plug specification corresponds to the OE-type referenced in factory parts lists.

• Compatible model years: 2012, 2013, 2014, 2015, 2016, 2017.
• Engine: 3.6L V6 (Pentastar series)
• Plug type equivalent: RER8ZWYCB4 / OE matching component.
• Gap: factory-set around 0.043–0.044 inches.

How do Champion iridium plugs differ from standard plugs for daily driving?

Iridium-tipped electrodes use a harder, finer precious-metal point than conventional nickel plugs, which typically yields a more concentrated spark and extended service life. That means more reliable starts and reduced ignition wear over time under normal driving conditions.

• Iridium center electrode for longer life and stable spark.
• Precise OE-style construction for correct heat range and fit.
• Reduced electrode erosion compared with standard plugs.

What should I expect during installation and maintenance?

Installation is straightforward for anyone familiar with basic ignition-service work: remove old plugs, check and clean the well, install new plugs to torque specification, and reconnect ignition coils. Because these plugs arrive with a factory gap near OE spec, most installations won’t require re-gapping unless vehicle service history indicates otherwise.

• Pre-set gap ~0.043–0.044 in — verify before final installation.
• Torque to manufacturer specification to avoid leaks or damage.
• Inspect ignition coils and boots while replacing plugs for best results.
