Coil Packs

Anyone familiar with or try Accel Super Coil Packs (140043)? Cheap enough, but don't know about gains, or if I'd need to tune for them. For now I want to keep my warranty and do simple mods like CAI, catback and some engine dress up.

Wires aren't a bad upgrade but they didn't add HP. Not on a stock car.
