gruppe m/tegiwa gruppe m gain for ep3

[gogzzzz]

Interested about gruppe m airbox system.
What interested me is real power gain compared OEM vs gruppe m airbox...people write 5-10 without mapp. and 15 hp mapped
So how much u gain ?
Also if someone change injen CAI for gruppe m.. does it significant better or it's just better sound?
Thanks !!

Injen CAI is slightly better over the GruppeM/Tegiwa. It has a smoother path for air and the filter has a built in velocity stack.
Not many people fit just an air intake. It's normally with other supporting mods before it's put on a dyno, so it's difficult to say how much BHP they have gained from the air intake.

I've just upgraded from the Injen to the Tegiwa M, hoping to gain a few horsepower from that Also eliminates the risk of hydrolock and sounds better!
