From The Manufacturer

The patented DENSO Platinum TT Spark Plug has a twin-tip design to improve ignitability and extend reliability. Until recently, this twin-tip design could only be found in the most technologically advanced automobiles. But now DENSO is offering this cutting-edge technology in a platinum-titanium design. Conventional platinum plugs use platinum for only the center electrode, while the DENSO Platinum TT Spark Plug features platinum on the center electrode and a titanium-enhanced alloy on the ground electrode for increased durability and minimized tip erosion. Both precious metals fight corrosion and erosion, ensuring superior spark performance and maximum spark plug life capable of extended operation in excess of 60,000 miles. In addition, the secondary tip on the ground electrode results in less obstruction of spark growth, while still maintaining the same gap. With this in mind, if your vehicle exhibits bad spark plug symptoms including slow acceleration, poor fuel economy, or engine misfires, consider DENSO for your performance spark plug replacement.

Expert Reviews

What reviewers liked

The Denso (4503) PK16TT Platinum TT Spark Plug is our choice for the best budget-friendly spark plug as it provides nearly all the performance-enhancing features of iridium but at a fraction of the cost. While a platinum spark plug such as this can provide less longevity than their iridium counterparts, the Denso 4503 isn’t far behind. It uses a platinum disc and electrode tip to provide solid performance. Those who purchased and reviewed this spark plug appreciated that it was compatible with a number of different vehicle makes and models, and came highly recommended by their mechanic. A couple of reviewers noted that they needed to re-gap their plug to fit, but most had no issues. With a price tag of about $3, this spark plug is a solid choice for those looking for a spark plug option on a budget. It has a rating of 4.5 on Amazon with nearly 400 people reviewing it, which we think goes a long way in convincing motor heads that this budget-friendly pick is just as good at improving engine performing as its more expensive counterparts.
It works faster compared to other plugs. It can help you save fuel. It has dielectric strength. It can withstand any stress.
If you’re in the market for solid all-around spark plugs that are easy on your wallet, look no further then Denso 4504 PK20TT Platinum Spark Plugs. These value-priced platinum plugs pack a whole lot of performance, efficiency, and durability for a downright reasonable price. Featuring a dual-platinum construction, with a platinum disc and platinum electrode tip, these spark plugs provide a reliable spark to generate smooth, reliable combustion of the air-fuel mixture. This translates to great engine dependability, fuel efficiency, and performance. Another impressive feature is purified alumina powder, which is used as an insulator to increase thermal conductivity for maximum longevity. There are a few faults that we found with these double-platinum spark plugs. Occasionally, the gap was incorrectly set on some of the plugs. This is why it’s critical that you inspect the gap and adjust it accordingly. In addition, these double-platinum plugs cannot match the quality, performance, and longevity that iridium spark plugs boast. Nonetheless, we believe that Denso 4504 PK20TT Platinum Spark Plugs are some of the best affordable spark plugs for your car, truck, or SUV.
