Big Sucker™ Stage I Air Filter Kit delivers improved horsepower and torque with a radius air inlet that provides unobstructed airflow.
The one-piece aluminum backing plate features hidden breather technology; each hidden breather is O-ringed at the heads and exits inside the mouth of the throttle body for a virtually closed-loop system, eliminating the need for external hoses or hardware.
The pre-oiled, high-performance filter is washable and reusable and is made from four layers of surgical-grade cotton for durable filtration.
All necessary hardware and clear instructions are included for a straightforward installation.
Handmade in the USA and engineered to provide noticeable performance gains. 🇺🇸
Fitment: will fit '88-'90 models; breather system is not applicable for these model years. For '91-'22 XL models with CV carb or Delphi EFI.
