    Rated 1 out of 5 by from Looks can be deceiving Looks good on the outside but the inside has loose welding material when you touch them they fall off and had to trim material off of the injector bungs to make it sit flush on the heads. Don't waste your money on this intake

    Are there any modifications required for this intake to work on a stock ls3?

    Asked by: X_mozy
    Speedmaster 746-1-148-051 should not require any modifications to run on a factory ls3 other than tuning
