got a freind who just brought a new gs430, he is looking for a intake for his car. what is a good one to get? what kind of power gain will be expert?
thanks

 

The only intakes I know of for sure that fits a 430 is the Injen and the SRT. I think Weapon R makes them as well, but not totally sure.
The SRT comes with a piggy-back ECU that is supposed to allow the factory ECU to take advantage of the increased air flow. The Injen doesn't have an ECU, but it is damn pretty.
You can see the Injen here; Injen intake
and you can check out the SRT here;
