    Holley 120-402 Details

    The oversized air cleaner look was king in the muscle car era, and we wanted to take engine bay styling back to that nostalgic time with these Holley Vintage Series Oval Air Cleaner assemblies. Each air cleaner assembly includes a durable cast aluminum Vintage Series finned lid, a stamped steel 1/2" raised baseplate, a 2.5" tall premium washable and reusable filter element, and all hardware needed for easy installation.These oversized oval air cleaner assemblies dwarf the competition with their size - measuring at 17" long x 9" wide - which will make your engine bay stand out in a crowd of stale old oval air cleaners. The included stamped steel baseplate is designed to fit single 4-barrel carburetors with a standard 5-1/8" diameter neck, and the 1/2" raise is enough to clear throttle linkages, carburetor bowls, and distributors without any worry of interference. These oval air cleaners are available in 5 unique finish options to perfectly match most Holley Vintage Series valve covers, and paired together, their styling creates an unsurpassed vintage vibe.

    Features:

  • Cast aluminum lid construction with stamped steel baseplate for optimal durability
  • 1/2 inch raised baseplate fits single 4-bbl carburetor setups with a 5-1/8 inch diameter neck and clears standard throttle linkages with ease
  • Oversized oval shape gives a true old school feel to your engine bay that can’t be replicated with standard sized oval air cleaners
  • Features a classic finned design with script Holley logo that was designed to be a perfect complimentary part for all Holley Vintage Series valve covers
  • Includes 2.5 inch tall, premium cotton gauze filter element for excellent filtration
  • Filter element comes pre-oiled, and is washable and reusable (filter care instructions are included)
  • Includes carburetor gasket and all mounting hardware necessary for installation
