Ignition coil plugs

Anyone heard of okada projects ignition coil plugs before? Evasive motorsports has them for the CR-Z for $900 which seems a bit expensive for coil plugs. I've been looking at some granatelli performance plugs for the EcoBoost that only cost $290 which is much less expensive then the ones for the CR-Z. If the coils offer decent performance gains and fuel efficiency then they may be worth the cost.

ITEM9 told me about them a few years ago, and he was stating that they were the next mod I should put on my car. I don't know if he has them installed (because I forgot to followup,) but I can't justify spending $1,000 on something that might be snake-oil wrapped in a pretty package and performance claims.

I would argue it will increase performance however not even close to enough justify the cost possibly not even enough to notice
However theoretically it COULD increase mpg enough to justify the cost if you drive like a grandma but it also depends on other engine upgrades and the spark plugs, in fact with crappy spark plugs it might even wear them sooner costing more money and negate any benefits you get from the coil pack
Id argue if you really wanted to get this wait till your coil packs go out a better, cheaper upgrade would be copper plugs
I dont think it would be worth it personally the coil packs should last the life of the car while they do recommend replacing them with the plugs, I dont see the point, replacing them with oem spec would help only a small bit and anything less such as generic aftermarket brands might even make them worse than your stock

If improved MPG is the goal, for what they cost you'd have to be saving LOTS of fuel to make up that cost premium. And notice that they don't bother to make a quantifiable claim on hp, torque or MPG numbers.
ITEM9 has a specific approach to modifications, different than many others, though not necessarily wrong.
