Twenty years on, your original throttle body-to-plenum rubber intake boots have fought the good fight. Years of exposure to heat cycling, engine vibrations and the occasional engine oil have likely left them beginning to show signs of age.

Designed with factory-fitment in mind, Turner Motorsport Silicone Throttle Body Boots install snugly and are engineered to offer high-durability under street and race conditions, including boosted applications. Not a simple silicone reducer, these boots were designed to feature the same internal features as the originals. With three-ply construction, these boots are slightly thicker than factory boots, and are compatible with screw-style clamps (use your preferred clamp, or select the kit with clamps, ES4135389).

The fact that they are less than half the price as OEM replacement boots is just an added bonus. Set of six included. Compatible with all intake plenums include US and CSL, including replicas that use an OE-style boot.
