You guys are just so practicalminded LOL.
Don't get me wrong, I'm the guy that spends $100 for 2 HP on a dyno, just to have it, just figured I'd point it out for those that didn't open the link. Every vehicle I have ever called my own has had a CAI, because I like the concept of an aftermarket CAI and the whistle is addicting when you pull air in.
Also, I should note, the dyno performed on these cars (from what I got from the article) was bonestock with custom tune vs. bonestock (except coils - replaced for MSD part) and custom tune.
This means that in a more modded platform, say upgraded turbos, E85, etc. there may be a better gain, or better reliability. It definitely can't hurt and is probably a very good peace of mind/support mod.
TLDR: Most likely the coils are worth it from a support/reliability perspective (we will have to see how they hold up) and peace of mind (given they do have the reliability expected -MSD is a pretty good company) but maybe not a noticeable power increase with just the coils
Edit: I re-read the article and on the SHO they even state the gains are above 5K. This is definitely not going to be felt on the street in most real world situations, and a minor improvement at the track (since the stock turbos lost a lot of steam at the top end. BUT, this supports my statement of being a good support mod, with a turbo that can keep pushing all the way to redline these may have a better gain.
