Silicone Boost Hose Kit RX-7 FD3S

The Pettit Racing Silicone Boost Hose Kit for your RX-7 provides a simple, reliable and effective way to upgrade your old OEM hoses, which commonly deteriorate and fail. These direct replacement silicone hoses are designed to exceed the extreme need of your RX-7 rotary-powered vehicle and improve boost response by eliminating expansion experienced with non-reinforced rubber factory hoses.

Our 4-ply Silicone Boost Hose Kit is sold in black because the colored hoses are nearly impossible to keep clean, and here at Pettit we like to keep it simple. Speed and beauty! All Pettit Silicone Hose Kits for the RX-7 come with stainless steel hose clamps for easy installation.

We make them a little longer to accommodate larger radiators and dimensional changes from crash damage, both of which can alter the position of the I/C. They can easily be trimmed with a razor blade.
