About This Product
These O-ring type intake clamps are sold as a pair and are constructed from high-grade stainless steel for superior corrosion resistance and durability. They come equipped with locknuts to ensure a secure, leak-free seal between your intake manifold and cylinder heads, which is critical for proper engine tuning and performance. These clamps fit 1957 to 1978 XL Sportsters and 1955 to early 1978 Big Twin models. They serve as a high-quality replacement for OEM part number 27066-85T. Using stainless steel clamps is a smart upgrade over standard steel versions, as they won't rust or degrade over time in the high-heat environment of the V-twin engine.
Manufacturer part number: 509190.
