what do you mean open hood vents?I want to run the JLT CAI and would like to leave the hood vents open. Has anybody done this? I thought I saw someone doing this.
What did you end up doing?I can say that if your filter gets soaked from the water pouring down through the vents, you will have problems drain hole or not.
Filter gets soaked, MAF even gets wet. You will get lurching, farting, and a cel.
Everything will need to be dried out.
Ask me how I know this!
