Message Factory is .044" I believe, and many here have found .035" will work much better. The reason is that under higher manifold pressure (15psi vs 9.5psi stock), it is harder for the spark to jump as far, or something to that tune. My car was missing at higher revs (5000+) and regapping them solved the problem completely. Best of luck with your car.
