Denso Iridium TT Spark Plugs

Denso Iridium TT Spark Plugs Focus on Total Performance (also: $16 Rebate Inside!)

Over the years, I have met many car enthusiasts that like to get their hands dirty under the hood. For them, performance is the most important aspect of the game – it’s more than just speed – but a marriage of economy and power. Believe it or not, one key component often overlooked in the performance equation is the correct spark plug.

If you have cruised through your local auto parts store, you have seen Denso’s full line of spark plugs. You might have purchased them in the past or recommend them to a friend. Recently, Denso introduced sometime new; something that underwent rigorous testing and creative thought. When it comes to the prized possession in your garage, Denso’s Iridium TT Spark Plugs might be right up your alley.

Research & Development

Denso’s scientists wanted the most durable alloy in the world for the Iridium TT Spark Plugs, so they invented an Iridium/Rhodium combination. Iridium is the metal most known for corrosion resistance, while Rhodium is inert against the most aggressive chemicals and corrosion. The combination of these two elements better resist oxidation and voltage ware, enabling Iridium TT spark plugs to outperform a traditional one, especially in the most severe engine temperatures and conditions.

Another proprietary technology comes in a 360-degree laser welding process. It’s used to manufacture the twin-tip spark plug with the world’s smallest diameter center electrode and anti-fouling characteristics. Such characteristics reduce heat while maximizing the firing potential and improving combustion.
