So my Blazers pretty much gone through an entire reconstruction project over the past couple of months. I found another job so I've had money to rebuild the transmission, fix up some rust spots, got a new bumper, and throttle body. Runs like a dream now, but I want to keep going with it. Now i have enough for a new intake system, and some headers. (Yes I'm going this route.) Now does anyone else on here with an aftermarket intake have any trouble running it with the stock fuel injectors??? And What intake worked best for you?
