Selection of the filter element depends on the amount of room available. We recommend fitting the tallest filter element you can, with a minimum gap of 1/2" (13mm) over the top of the filter for air to circulate. If rampipes are used there must be a gap between the end of the pipe and the underside of the top of the filter: 3/4" (19mm) is an absolute minimum, and 1 1/4" (32mm) is preferable.

Note: Most types of Megaflow filters are available as either flat or domed (sausage) shape (see JC70 illustration of sausage type filter). Sausage-type filters must be special ordered from the factory.

Please choose a link for dimensional information for each filter size range. All Megaflow filters are defined by internal height (A) dimension. All dimensions are in millimeters (divide millimeter dimension by 25.4 to convert to inches).

Baseplates for Megaflow filters are available as blanks (aluminum) or pre-cuts (red powder coated steel) to fit a variety of carburetors and injectors. Blanks are stock items and application-specific pre-cuts are typically special order from the factory. Contact us for further information.
