unfortunately, i just installed my Injen RD Series CAI and the engine light is on....there is no way to prevent this due to the solonoid attached to the stock airbox. I am lookin for a way to remove the fuse for the solonoid so there is no longer the engine light. Although the engine light is on, the intake is not causing any damage. It is basically like an incomplete ciruit that is looking to be completed, but cant. If i hear any news about the fuse situation i will be sure to inform you.
