      Significant Flow Increase for Measurable Power. Featuring dual 58mm throttle bores, the BBK Twin 58mm Throttle Body allows up to 1000 CFM of airflow—approximately 25–35% more than the stock component. This substantial increase directly contributes to a 7–12 rear wheel horsepower gain, making it an ideal bolt-on enhancement for engines running cold air intakes, performance manifolds, or custom tunes.

      Built to Last. Built to endure high-performance demands, the BBK Twin 58mm Throttle Body is CNC-machined from 356 aluminum alloy for exceptional strength, durability, and dimensional accuracy. This high-grade construction ensures a tight and precise fit, reducing turbulence and maintaining consistent airflow characteristics.

      Long-Term Reliability. The BBK Twin 58mm Throttle Body features an O-ringed throttle shaft and double-sealed roller bearings for superior sealing and smooth operation. This internal engineering minimizes wear, reduces friction, and ensures dependable performance under both daily driving and demanding load conditions.

      Installation. Putting this BBK Twin 58mm Throttle Body on your Corvette C4 takes 30 minutes to install.

      Warranty. There is a limited warranty on this product.

      Application. The BBK Twin 58mm Throttle Body fits 1989-1991 Corvette C4 models.
