You can upgrade your air intake system, but a stock intake manifold will still muffle the power gains that come from more oxygen. Clunky factory cast iron manifolds are built from dinosaur-aged designs that rob your throttle of tire-chirping horsepower every time you get behind the wheel. Step up from stock with BBK Intake Manifolds. These monsters not only unlock bone-crunching power gains, but they also give your engine compartment a menacing look.
The technology that lies at the heart of BBK Intake Manifolds is 15-years in the making. The power-addicted engineers at BBK have painstakingly tested and tinkered on dynos and the street to ensure that you get the maximum real-world energy delivered to your rear wheels-upwards of 24 horses (varies by engine).
Be prepared for an afternoon of under-the-hood time to install your BBK Intake Manifold. It's an involved job, but the results will blow you away. Backed by a 1-year warranty.

Supplied throttle body bolts were too long. Removed 1 cm off the top bolt because it extended out onto the EGR block off plate. Removed .5 cm off the bottom bolts because they bottomed out in the intake before snugging up the throttle body. The shoulders of the intake bolts extended below the intake itself. I used a die to cut the threads up .5 cm on the shoulder. Intake = 85cm Throttle body = 80cm Supplied gasket = 79cm Called BBK - was told "no one else has complained about it"

I look at getting a used LS6 manifold to go along with my heads and cam installation but could not find one for less money than I payed for this manifold and supposedly this will outflow a LS6 manifold. Yes I know that the FAST outflows them all but I don't have a grand to lay out for the FAST plus I personally like the look of the BBK. I thought the hardware included was not very good automotive grade quality. As for the heat soak issue and weight issue, I don't drag race much, maybe go to the track 6 times a year just for fun.

I choose this manifold mostly for the appearance, but also because of the potential it will have for porting and installing NOS nozzles. The weight and heat transfer were initial issues of mine, but the weight is minimal, and the fact that the aluminum conducts heat is a non-issue. The install was the exteremely easy and took only about an hour, much better than Gen 1 small blocks. I did also choose BBK because it uses OEM gaskets which makes for easier maintainence down the road. The only cons I would list are not very significant. It did have a very very minor cast flaw, which was a small amount of aluminum at the opening of the runner and will be easily ground off (I installed without grinding it off as it is extrememly small and will be porting later on). Secondly, and this is not an actual issue with the intake, but I find it odd that BBK does not offer an 85mm throttle body to match the intake for Corvette applications. Overall, I would say this is a great buy and have no real complaints. IT looks GREAT too.

I love the quality of the manifold. The install was alright, although there are a few things they don't tell you. Like, i had to bend the outlet on my stock fuel regulator to a 45 degree angle to clear the manifold. And the bolt pattern on the back of the block is mad to accommodate 2 styles of idle control valves. Whichever one you don't use, needs to be plugged and the manifold does not include one(i used a bolt). If you are experienced enough to install the manifold, then all the little tweaks needed shouldn't be an issue.
