Sixity Auto DENSO Iridium spark plugs 4pc for Toyota Camry 2.5L (2010–2017) — 0.4mm iridium, pre-gapped 0.044

DENSO Iridium Power spark plugs — a four-pack performance replacement engineered for Toyota Camry 2.5L L4 models from 2010 through 2017, featuring a 0.4 mm iridium center electrode and a 0.044" factory gap.

These four spark plugs are an OE-quality replacement designed to deliver a stronger, more consistent spark than conventional plugs. DENSO's Iridium Power line pairs a fine 0.4 mm iridium tip with a tapered cut and U-groove ground electrode to concentrate spark energy while resisting wear. The set is supplied as a genuine DENSO component intended for Camry 2.5L L4 engines (model years 2010–2017, including hybrid trims where listed) and comes pre-gapped to 0.044" for direct installation.

How do these spark plugs affect everyday driving?

Iridium-tipped plugs create a focused, reliable spark that can support more complete combustion compared with older nickel designs. Drivers commonly notice steady idle behavior and responsive throttle feel when plugs are in optimal condition. They are suited for routine replacement intervals where long-term durability and stable performance matter.

• 0.4 mm iridium center electrode concentrates spark energy for consistent ignition
• Tapered tip and U-groove ground electrode improve flame propagation
• Pre-set 0.044" gap for Camry 2.5L L4 — ready to install
• Designed to tolerate high temperatures and performance load

Will these fit my Toyota Camry model and engine?

This four-pack is specified for Toyota Camry 2.5L L4 engines covering model years 2010 through 2017, including certain hybrid trims in the compatible range. The plugs come as direct replacements built to DENSO OEM standards; always confirm fitment with your vehicle’s model/year and VIN or parts lookup before purchase. If your Camry uses the listed engine and plug gap, no modification should be necessary.

• Compatible with Camry 2.5L L4 (2010–2017) — check specific trim compatibility
• Pre-gapped at 0.044" to match factory specifications
• Pack contains four plugs — enough for a full four-cylinder replacement
• Genuine DENSO packaging and manufacturing for OE-level fit

What technical features set Iridium Power plugs apart?

DENSO Iridium Power plugs combine a very fine 0.4 mm iridium center electrode with a tapered tip and a patented U-groove design to maximize spark exposure and improve combustion efficiency. The iridium alloy (approximately 90% iridium composition as specified in manufacturing descriptions) and a 360-degree laser welding process increase electrode durability and ensure a secure bond. These design choices prioritize sustained performance under higher temperatures and longer service intervals.

• 0.4 mm iridium tip for concentrated, efficient spark
• Patented U-groove and tapered cut to enhance flame travel
• 360-degree laser welding for electrode durability
• Rated to withstand high combustion temperatures common in performance applications

How should I install and maintain these plugs?

Installation is straightforward for anyone comfortable with basic engine work: remove old plugs, inspect threads and torque specs, and install the new plugs hand-starting the threads before torquing to the manufacturer's spec. Because these arrive pre-gapped, you typically don’t need to adjust the electrode gap; still, verify gap and torque during installation. Periodic inspection during scheduled maintenance helps ensure peak ignition performance.

• Start threads by hand to avoid cross-threading, then torque to Toyota specification
• Verify the 0.044" gap before final installation
• Inspect ignition coils and boots when replacing plugs
• Follow vehicle maintenance intervals for optimal longevity

Who is this for: This four-pack of DENSO Iridium Power plugs is aimed at Toyota Camry owners with the 2.5L L4 engine who want a direct-fit, OE-quality upgrade or replacement. It's a good choice for DIY mechanics, fleet maintenance, and drivers seeking improved ignition stability and longer-lasting plugs compared with standard copper or nickel options. Confirm year, engine code, and gap compatibility before purchase to ensure proper fitment.
