Ignition Projects Performance Ignition Coils
2004–2006 Scion xA / xB 1NZ-FE 1.5L
IP-A137405
Overview:
The Ignition Projects Performance Ignition Coils are engineered specifically for the 2004 to 2006 Scion xA and xB models equipped with the 1NZ-FE 1.5L engine. These coils feature an integrated high power amplifier that significantly enhances ignition performance beyond stock capabilities. Designed for enthusiasts seeking improved throttle response, combustion efficiency, and overall engine performance, these coils deliver a powerful and consistent spark that supports both naturally aspirated and forced induction setups.
By producing up to four times more spark energy than factory coils, Ignition Projects coils ensure a more complete and rapid combustion process. This results in smoother engine operation, better fuel efficiency, and potential gains in power output. Whether you are upgrading for daily driving or competitive motorsports, these coils provide a reliable ignition solution tailored to your Scion.
Key Features:
Ignition Projects Performance Ignition Coils incorporate advanced technology and meticulous craftsmanship to deliver superior ignition performance. Key features include:
- Integrated high power amplifier built into each coil for enhanced spark energy
- Generates up to four times more spark energy compared to stock ignition coils
- Ultra-fast multi-spark discharge producing up to 10 sparks per ignition cycle at high RPM
- 100% increase in spark amperage for improved ignition reach and combustion speed
- Optimized for both naturally aspirated and forced induction engines
- Handmade in the USA with strict quality control overseen by expert engineers
- Double quality inspection including oscilloscope testing to ensure consistent performance
- Utilizes patented Ignition Projects technology developed through professional race team collaboration
Construction & Design:
Each Ignition Projects coil is handcrafted in Tustin, California, under the supervision of experienced engineers, including leadership from Japan. This hands-on approach ensures exceptional build quality and reliability. The coils are constructed with premium materials designed to withstand the rigors of high-performance driving and extreme engine conditions.
The internal high power amplifier circuit is precisely engineered to maximize spark output without compromising durability. This robust design supports sustained multi-spark discharges at elevated RPMs, providing consistent ignition under demanding conditions. The attention to detail in manufacturing guarantees that each coil meets stringent performance and longevity standards.
Performance & Sound
By delivering a stronger and faster spark, these coils accelerate the ignition and combustion process, which can lead to improved throttle response and smoother engine operation. The enhanced spark energy helps ignite the air-fuel mixture more completely, potentially reducing misfires and improving overall engine efficiency. While primarily focused on performance gains, the improved combustion can also contribute to a more refined engine sound with reduced hesitation during acceleration.
Installation & Fitment:
Designed as a direct replacement for the factory ignition coils on 2004–2006 Scion xA and xB models with the 1NZ-FE 1.5L engine, installation is straightforward and requires no modifications. The coils fit into the existing ignition system connectors and mounts, making the upgrade accessible for both professional installers and knowledgeable enthusiasts. Standard hand tools are sufficient for installation, and no additional tuning is typically necessary.
