I'm looking at getting a induction kit for my sei but i'm stuck between a Gsr kit and a CDA Induction kit...of the two which has the best power gains etc?
I suspect nobody has done back to back on a dyno/rolling road, so no one really knows. I think the GSR is substantially cheaper, so would be inclined to go for that.
The CDA isn`t an induction kit. You still need hoses to make it one. If you want to go for a BMC filter then go for the DIA. It is a cheaper and better flowing filter. You still need to make some hosing for it.
