Yeah basically. But those who said that are kinda ragging on you, they dont like it and think its a waste. I'm not saying it is or it isnt its everyone's own opinion. But it is not a good idea to block your intake IMHO, bad things can happen. Get a pryo, and turn up the pump and you will be able to roal coal. Dont block the intake cause when you need to accelerate, performance will be way down, and all you would be doing is going slow and putting out black smoke.
