4x Denso Iridium TT Spark Plugs for Ford Escape ZC ZD Fiesta CB1 CCN WP WQ WS WT

DENSO is one of the world's leading innovators and manufacturers of ignition technology, including spark plugs.DENSO was the first company to produce long-life automotive Iridium spark plugs, and invented the world's smallest, most efficient 0.4mm Iridium tip.

With 97% market coverage in Australia and DENSO's unsurpassed reputation for technological superiority.

Engineered with a 0.4Mm diameter iridium centre electrode and a 0.7Mm platinum-tipped ground electrode; the iridium tt delivers more complete combustion giving you superior fuel economy and increased power.

In order to maximally prevent the quenching effect, the ground electrode needs to be made as smallas possible. Traditional ground electrodes could not be made too small without reducing groundingstrength or increasing electrode wear. However, we've managed to attach a fine 0.7mm diameterplatinum electrode using a 360° laser welding technique.

Using DENSO's exclusive Iridium alloy, which has a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark plug voltage requirements and greatlyimproving ignitability.

• Engineered with the smallest tip in the market, the DENSO Iridium TT spark plug delivers more complete combustion, giving you superior fuel economy over any other plug.
• The Iridium TT is designed to last beyond 100,000 km.
• Less stock, same coverage: TT Plugs cover many applications with fewer part references.
