If I decide to go for a stealth install and want to drill into the bottom of the sleeve at the back of the lid where it meets up with the maf, what would be the best way to aim the nozzle? Would it be bad to aim it straight at the maf when it's only this close or would the nitrous still function properly? Would it be better to aim it towards the front and let the incoming air "pull" the nitrous back through the maf so there's more time for it to react? Sorry for the dumb question .

 

point it towards the front of the box. Spraying it directly at the MAF will cause it to freeze and become damaged.
