The OKADA PROJECTS Plasma Direct Ignition Coil Set SD335151R is a high-performance ignition upgrade designed for the Audi RS3 Sedan with the 2.5L turbocharged 5-cylinder engine (DAZ/DNW).
It replaces the factory coil packs with a more powerful ignition system to improve combustion efficiency and engine response.
Key Specifications
- Brand: OKADA PROJECTS (Japan)
- Product code: SD335151R
- Vehicle: Audi RS3 Sedan
- Engine: 2.5L turbo inline-5 (DAZ / DNW)
- Fitment: Direct replacement coil pack set
- Installation: Plug-and-play (no wiring modification)
Main Technology (Plasma Direct System)
The coil incorporates a built-in high-power amplifier that boosts ignition energy and generates multi-spark ignition events during each combustion cycle.
Key features include:
1. Multi-Spark Ignition
- Instead of one spark, the system produces 3+ ultra-fast sparks per cycle, improving flame propagation in the cylinder.
2. Higher Secondary Current
- Secondary ignition current can be about double the OEM coil, creating a stronger spark for better combustion.
3. High-RPM Stability
- Multi-spark events occur in microseconds, maintaining ignition stability even at high RPM or tuned engines.
Performance Advantages
Installing the Plasma Direct coils typically delivers:
- ⚡ Stronger spark energy for improved combustion
- 🚀 Improved throttle response and acceleration
- 📈 Small horsepower & torque gains across RPM range
- 🌀 Smoother boost build-up on turbo engines
- 🔧 More stable idle and easier cold starts
- ⛽ Potentially better fuel efficiency
- 🌱 Reduced emissions due to more complete combustion
Some aftermarket listings report around ~3% power gain depending on engine setup.
Best Use Cases
This ignition upgrade works best when the RS3 has:
- ECU tuning (Stage 1–3)
- Higher boost turbo upgrades
- Performance spark plugs (Iridium)
- Ethanol / high-octane fuel setups
For heavily tuned EA855 2.5T engines, stronger ignition helps prevent misfire under high boost.
✅ Simple summary:
The Okada Plasma Direct SD335151R is a premium ignition coil upgrade for the Audi RS3 that increases spark strength, produces multi-spark combustion, and improves engine response, especially on tuned turbo engines.
