Re: Anyone on here done the GTA intake mod?
I did the mod on my last 156 and TBH it didn't make a lot of difference.
Maybe slightly better throttle responce, (although I may have imagined it) but the noise level was about the same.
There isn't a lot wrong with the 156's induction as standard so gains from changing it will be minimal, maybe 1-2bhp at best IMO.
Obviously if you have other mods done to the engine, cams etc them modifications to the intake will have more effect.
