Show original supplier description
The Ignition Projects IP-A137405 is a high-performance ignition coil set engineered with patented technology to significantly enhance your vehicle's ignition system. The spark amperage is increased by 100%, allowing for a greater volume of fuel molecules to ignite, thereby accelerating the combustion process. This improvement is beneficial for both forced induction and normally aspirated engines. Engineered in Japan and meticulously handmade in Santa Ana, California, USA, each IP Ignition Coil undergoes rigorous testing with an industrial-grade oscilloscope to ensure the highest level of quality and performance. These coils are a direct plug-in replacement, requiring no modifications for installation. This ignition coil set is compatible with the following vehicles equipped with the 1NZ-FE 1.5L 4-cylinder engine: Toyota Echo (2001-2005), Toyota Prius (2001-2018), Toyota Yaris (2007-2018), Scion xA (2004-2006), and Scion xB (2004-2006). Ignition Projects offers a one-year warranty on all IP Ignition Coils, covering both daily drivers and competition race cars.
