6 PCSNEW — DENSO #4503 PLATINUM T T Spark Plugs — PK16TT

Denso is a powerhouse in Japanese automotive parts, and their Platinum Twin Tip (TT) plugs deliver great performance without the premium price tag of pure iridium. What makes the TT design special is the unique 1.1mm platinum center electrode paired with a titanium-enhanced ground electrode. This twin-tip structure dramatically focuses the spark energy, leading to better combustion, especially noticeable during cold starts and acceleration.

Key features that stand out:

• Unique Twin-Tip Structure (TT): Improves ignition efficiency and reduces voltage requirements.
• Titanium-Enhanced Ground Electrode: Increases durability and minimizes tip erosion over time.
• Laser Welding: Ensures precision construction for optimal gap and heat transfer.

Pros:

• Excellent affordability and high-quality Denso engineering.
• The Twin-Tip design provides superior ignitability compared to standard platinum plugs.

Cons:

• Lifespan is generally shorter than premium iridium options (closer to 60,000 miles).

Best for: The budget-conscious driver looking for the best performance increase per dollar.

Expert Opinion: Denso’s TT technology is genuinely effective for maximizing combustion in older engines like the 3.5L V6. While they may not hit the 100k mileage mark of iridium, the immediate improvement in throttle response is often worth the trade-off.

6 pc NGK Iridium IX Spark Plugs compatible with Honda Ridgeline 3.5L V6 2006-2008

Comparison Short Insights

When evaluating the best options for your 2007 Ridgeline, remember that you are typically choosing between longevity (iridium) and specific combustion enhancements (platinum TT).

The NGK Iridium IX and DENSO PLATINUM T T stand out as the established leaders in ignition quality; if you prioritize the absolute smoothest idle and quickest throttle response, these are your top contenders. However, the Denso will require replacement sooner than the iridium options.

For those wanting the longest possible interval between tune-ups, the A-Premium Iridium Platinum option offers exceptional durability, promising up to 100,000 miles of service. It’s a great balance of longevity and cost-effectiveness.

The A-Premium Set of 6 Ignition Coil Pack and Iridium Spark Plugs is in a category by itself. It’s the superior choice for major maintenance, offering complete peace of mind by replacing the entire ignition circuit. This is especially relevant given the age of the 2007 model year.

Best Spark Plugs For 2007 Honda Ridgeline FAQ

How often should I replace the spark plugs in my 2007 Honda Ridgeline V6 3.5L engine?

For the original factory plugs (typically Denso or NGK long-life iridium), Honda recommends replacement every 105,000 miles. However, if you are using high-quality aftermarket iridium plugs (like the A-Premium or NGK Iridium IX), you can expect a similar service life between 80,000 and 100,000 miles. For standard platinum plugs, plan on replacing them closer to the 60,000-mile mark.

What are the signs that my spark plugs need replacing?

Common symptoms include rough idling (the truck shakes when stopped), engine misfires (especially noticeable during acceleration), difficulty starting, a noticeable drop in fuel economy, or a lack of power. If the Check Engine Light flashes, this often signals severe misfires, which may indicate issues with the ignition coils as well as the plugs.

Should I choose Iridium or Platinum spark plugs for my Ridgeline?

Iridium is generally superior for modern V6 engines like the 3.5L. Iridium is harder, allowing for a finer wire tip that requires less voltage to fire and offers superior durability and heat resistance. Platinum plugs (like the Denso TT) offer great performance and are more affordable but usually don’t last as long as iridium options. For the best longevity and performance stability, iridium spark plugs are recommended for the 2007 Ridgeline.

Is replacing the spark plugs on the 2007 Ridgeline a difficult DIY job?

The job is moderately difficult. While the front bank of three cylinders is easily accessible, the rear bank of three requires removing or moving the intake manifold. This makes the job more time-consuming and requires careful attention to vacuum lines and gaskets, but it is certainly doable with the right tools and a repair manual.

Do these spark plugs come pre-gapped, or do I need to gap them myself?

Most modern iridium and platinum spark plugs, especially those made by reputable brands like NGK and Denso, come pre-gapped to the correct specification for the 3.5L Honda engine (usually around 0.044 inches, depending on the plug). It is strongly advised not to use a traditional gapping tool on fine-wire iridium plugs, as you can easily damage the delicate tip. Always confirm the required gap in your owner’s manual against the plug’s specifications.

If I buy a coil and plug kit (like the A-Premium kit), should I replace the ignition coils if they aren’t faulty yet?

Yes, for a 2007 model, replacing the coils as preventative maintenance is a very smart move. Ignition coils have a finite lifespan, and an aging coil will put stress on the new spark plugs and reduce performance. Replacing the coils at the same time guarantees that your new best spark plugs for 2007 Honda Ridgeline are receiving the strongest possible current, maximizing engine performance and reliability.
