These six genuine DENSO Iridium TT spark plugs are a direct-fit replacement for Toyota Tacoma 3.5L V6 models (2016–2017), engineered for consistent ignition, longer life, and improved combustion efficiency.

Whether you're performing a scheduled tune-up or addressing misfires, this 6-piece set from Sixity Auto supplies OEM-quality DENSO Iridium Twin-Tip plugs with a 0.040" gap. Built with a 0.4 mm iridium center electrode and a 0.7 mm platinum ground tip, these plugs are designed to resist wear, maintain spark energy, and help the engine burn fuel more completely compared with conventional plugs.

How do DENSO Iridium TT plugs improve engine performance?

DENSO's Twin-Tip technology concentrates spark energy at a precise point, promoting faster flame propagation and more consistent combustion across cylinders. That steadier ignition can reduce misfires and help the engine run smoother under load.

• 0.4 mm iridium center electrode for stable, high-energy sparks
• 0.7 mm platinum ground tip for durability and consistent gap
• Patented ground electrode shape for improved flame travel
• Engineered to reduce erratic starts and partial combustion events

Will these plugs fit my Toyota Tacoma and do they require modification?

These plugs are specified for the Toyota Tacoma 3.5L V6 model years 2016 and 2017 and come pre-gapped to 0.040" to match factory specifications. They are direct replacements that install like the original equipment parts without special adapters or modifications.

• Direct-fit for Tacoma 2016–2017 3.5L V6
• Pre-gapped to OEM 0.040" specification
• Sold as a 6-piece set — full engine coverage
• No extra parts or re-machining required for standard installations

How long can I expect these spark plugs to last compared to standard plugs?

Iridium and platinum alloys resist electrode wear much longer than standard copper electrodes, extending service intervals under normal driving conditions. Lifespan will vary with driving habits and engine tune, but these DENSO Iridium TT plugs are designed for extended durability and stable performance over many miles.

• Iridium center tip minimizes erosion and maintains gap longer
• Platinum ground tip adds wear resistance at the opposing electrode
• Less frequent gap drift means longer consistent ignition
• Suitable for routine service intervals recommended by the vehicle manufacturer

What benefits can I expect after installation?

After installing DENSO Iridium TT plugs you should notice crisper starts, steadier idle, and more uniform power delivery across the rev range when the rest of the ignition system is in good condition. They are also intended to help reduce the likelihood of fouling and incomplete combustion events.

• Improved ignition reliability and reduced misfires
• More complete fuel burn for consistent throttle response
• Extended plug life reduces maintenance frequency
• OEM-quality fit and finish from a recognized supplier

Who is this for: This 6-pack of DENSO Iridium TT spark plugs sold by Sixity Auto is ideal for Toyota Tacoma owners (3.5L V6, 2016–2017) who want a direct OEM-quality replacement that prioritizes durability and consistent combustion.
