Throttle Body Shaft Seals: EVO

These are the seals that seal the throttle body inlet valve shaft (oftentimes called a butterfly valve). This is one of the most common sources of a boost leak in an EVO. When your EVO first rolled off the assembly line, the original seals were soft, supple and provided an excellent seal. Of course, over time these seals get worn and hard and tend to loose their sealing ability. No need to fret, replace them with these. 

Shaft seals are available in two different styles:

• rubber
• metal-reinforced rubber

The rubber seals are the seals we've been selling for years and years without complaint. The metal-reinforced seals are claimed by their manufacturer (SKF) to be metal encased.  However, they are actually externally rubber, internally reinforced with metal. 

NOTE: We used to sell seals that we referred to as "military spec", which were seals encased in an outer metal shell.  We have none of these in stock and are currently unable to source them.

Application: EVO (I-IX).
