Eric Hsu
Cosworth Engineer (provides support for Sierra Sierra)

“On the Sierra Sierra EVO, the Plasma Quad-Pac and Plasma Lift performed flawlessly. It was the first time I was able to set it and forget it and not have to struggle with spark plug gaps. We installed the Okada ignition system, I adjusted the Plasma Lift to 16.5v, and gapped the plugs larger than ever before and the ignition has not had a single misfire to date. I’m going to use Okada Projects on all of the engine projects that I’m involved in from here on.”
