Review on ATP Automotive Graywerks 106001 Engine Intake Manifold: High-Performance Product for Enhanced Engine Efficiency by Calvin Chavva

The gauge clearly states that there is a metal insert installed in the intake. You then use a "stove pipe" in the bottom air intake so you have an air gap and a metal sleeve protects the plastic top air intake. A reception plan is sent without any metal casing. The instructions don't specify a metal grommet and also state that you must make sure you are using the correct size stovepipe or you will MELT the air intake. The whole point of buying this kit is to avoid melting. WTH. All descriptions and photos show and say it has a metal sleeve. It is not. A complete waste of time and money for a textbook example of bait and substitution. Describe and show one product, then switch and send another product to the customer.
