Oval A/C Element for 1235 & 1236

The Oval A/C Element for 1235 & 1236 (part number 1220) from Edelbrock is a replacement air intake filter designed for high-performance carburetor systems that demand consistent fuel atomization and engine breathing. This component serves as the critical filtration stage in Edelbrock's renowned intake manifold packages, protecting engine internals from airborne contaminants while maintaining optimal airflow velocity into the combustion chamber. Whether you're running a street application, weekend cruiser, or modified performance setup, a clean, properly fitted air element directly impacts throttle response, fuel economy, and overall engine longevity.

The oval design of this element maximizes surface area relative to its compact footprint, reducing intake restriction while trapping particulate matter with precision-pleated media. Edelbrock's engineering ensures that the 1220 element fits seamlessly into the 1235 and 1236 manifold assemblies, maintaining proper seal geometry and preventing unmetered air leakage around filter margins—a common cause of rich running conditions and carbon buildup. The lightweight construction (1.33 lbs) minimizes thermal mass, allowing the intake charge to remain cooler and denser, which translates to measurable gains in volumetric efficiency on carbureted and naturally aspirated engines.

Technicians and enthusiasts running Edelbrock's 1235 or 1236 carburetors should replace this element every 12–15 months or 10,000 miles, depending on operating environment and air quality conditions. Off-road and dusty environments demand more frequent service intervals to prevent performance degradation. Installation requires no tools beyond standard automotive hand tools, and the element's compact 8.4 x 4 x 19.2-inch profile ensures it fits under most factory and custom air cleaner assemblies without modification. For anyone serious about preserving carb tuning precision and engine health, this OEM Edelbrock replacement is a straightforward maintenance investment with zero-compromise fitment.
