Intake Hose/ Boot

Intake Hose/ Boot

High quality 4-layers silicone construction.

COSMO Racing Silicone Throttle Body Intake Boot allows maximum airflow through the stock manifold system. The stock rubber intake boot on your car leaves power on the table; the bellows design can create flow turbulence, thus optimum engine power never reached. By removing the stock molded rubber intake boot and replacing with this heavy duty and quality mandrel made intake boot, maximum airflow through the throttle body is reached. The maximum airflow results in better throttle response and more horsepower. Last 4-times longer than stock rubber boot. No more dry-rotting rubber!
