    300-122 is rated 3.0 out of 5 by 2.
    Rated 4 out of 5 by from I recently bought this item and left it in the box until yesterday for installation for my vehicle. And come to realize there was 2 missing intake studs, 2 missing washers and 2 missing nuts. I will get pictures for reassurance for you guys but over great product. But there is no place in my town to get these specific hardware was willing to know if you guys at jegs could send me the material I need to get intake fully bolted down on vehicle. Thank you.

    ?#1.How much of a stock hood would you have to modify to get clearance for the intake? ?#2. How much hp. Will you get with this intake?

    Asked by: Error4you
    The hoos clearance will depend on the application. The HP is also dependent on the engine and the components being used. This will make a lot of power.
