    I just received mine today. I can't wait to install them on my new engine. contrary to what the description of the product says (Machined from solid aluminum with a Cosworth blue anodized finish) mine are very much not blue they are gray, but they still look great.

    Fit great no issues, but just to let you know they do not come with new gaskets. Have to reuse old ones or order new ones. The gaskets are stainless though. Love the fasteners they come with.

    QUESTIONS & ANSWERS

    • Q: gaskets  danielspead155893 years ago

      do you still use gaskets with this delete kit or no gasket needed since both the block and plates are flat faces ?
      • 0 of 0 people found the following answer helpful

        A:  Gaskets should be used with these plates, and the gaskets need to be purchased separately.

    • Q: P2433 code  Mattfryday1874 years ago

      If I delete the air pump will this code go away? I just changed out my maf sensor and its still going off. But the p2431 code went away. Also will it affect my emissions getting rid of it or having the code going off?
      • 0 of 0 people found the following answer helpful

        A:  Air pump deletes will cause a check engine light and the only fix would be the calibrate the ECU to ignore it. These parts are meant for offroad use only and we cannot comment on emissions.

    • Q: use  manny d4 years ago

      how is this useful besides weight reduction and faulty codes? does this help in power and airflow??
      • 0 of 0 people found the following answer helpful

        A:  This is mainly just to delete the air pumps and slight weight reduction. There are not really any other benefits to this piece.
