FAQ

Is the aFe 51-82502 CARB legal in California?

No. This part does not carry a CARB Executive Order, so it is not legal for sale or use on pollution-controlled vehicles registered in California or other states that follow California emissions standards. aFe intends it for off-road and competition use in those states; it remains street-legal in states following federal EPA emissions rules.

This Magnum FORCE Stage-2 Si intake fits the 4.7L V8 in the 2005-2009 Toyota 4Runner and the 2005-2009 Lexus GX470.

How is 51-82502 different from 51-81162?
