Quality component easy to install. Haven’t had it long enough to determine if it helps mileage or not. By design it has to reduce turbulence and improve airflow in manifold.

Shipped fast and packaged well. Very easy to install. Came with removable center plug for boost guage fitting. Price was not overly expensive. Could not tell if it made a difference in air flow, but it is logical to assume it does once you remove that big heater element. Quick, cheap, and easy mod.

You don't need this for your early 99. Be sure to always check the handy "fitment" tab.

Nice piece, fits perfect and has a nice o-ring on it to seal.

Awesome nice looking product and the port to add a boost gauge is a great addition to an already great item! Riffraff products are top notch!

Does everything it advertises.

Fits and functions as it should.

Fit perfectly hopefully improve the airflow getting that heater out of the intake Y pipe
