How much of an improvement will you see with our multiport injection...? Spacers were more useful for carb/throttle body injection I believe. Without a pre and post Dyno chart, I would pump the cost of a spacer towards a stickier set of tires. Easy DIY and pretty to look at might be it's main advantages.

If the $200 invested on Dyno runs showed some HP/torque increase, I would see this product selling better.
