Marcucci Motorsports now stocks Miata phenolic spacers

I have one on mine. Like everyone says, it isn't something that causes a noticeable power increase. I did it because it's cheap and "probably" dosen't hurt performance. I'd be very suprised if one showed any difference on a dyno. My gasket is from Powergasket on EBay.

That about sums it up. :flower:
