The 99-02 truck intakes are limited in the size of the throttle body opening. Now we take that opening to the limit with the 80mm billet throttle body. This piece is constructed with our usual 6061 aluminum body anodized 'Carbon Black' and full ball bearing supported throttle shaft for durability. The body bolts directly to the stock intake manifold without any modifications provides over 1000 cfm for a 10-12 hp improvement.
